A Discussion of the Design of Children's Space in German Museums——Museums in Germany as the example

Journal of Xi'an University of Architecture & Technology (2011)

Yang Yang

The subject of for is designated in 2006 for the Museum Day by International Museum Association.It is a common sense that the museum should take it seriously that the kids visiting the museum play an important part in the adolescent's education,although there are still problems in the practice.For instance few museums are considerate in the services for adolescents in the initial stage of construction nor in the later process of maintenance.Based on the perfect cases of German museums,the paper tries to explore spatial design techniques to make it possible for adolescents to enjoy and experience museums.

[Land Use Pattern Change and Regional Sustainability Evaluation of Wetland in Jiaogang Lake].

PubMed (2015)

Yang Yang Yimin Cai Yanying Bai Weiping Chen Xiu-chao Yang

Changes in land use and sustainability evaluation of wetland in Jiaogang Lake from 1995 to 2013 were analyzed, based on the land use change models and an index system, supported by RS, GIS, and social statistical data. The results showed: (1) dry land, paddy field, and building land were the predominant landscape in the study area. The arable land was mainly converted during 1995-2000, which was driven by the extension of agriculture, and the building land increased significantly during 2010-2013, which was driven by the tourism development. (2) Compared to the beginning research area, the building land increased by 123.3%, and the wetland decreased by 23.15%. The land system was at risk for a low proportion of wetland, scarcity of unused land, and the fragmented landscape. (3) The regional sustainability results were bad level, bad level, poor level, good level, and poor level during the different periods, with some room for improvement. (4) The fitness of regional sustainability in study area yielded satisfactory results in 2010, owing to the rapid growth of regional productivity and the regional stability. Since 2010, with the increasing environmental load, the regional sustainability fell down to the poor level. The obstruction of sustainable development is necessary to be addressed in the study area.

Quantitatively Evaluating the Ecological Product Value of Nine Provinces in the Yellow River Basin from the Perspective of the Dual-Carbon Strategy

Land (2023)

Yang Zhang Zijun Ma Sun Meng Jianing Song Yang Yang

At the 75th session of the United Nations General Assembly, China formally proposed the goal of achieving carbon peak by 2030 and carbon neutrality by 2060, which is called the dual-carbon strategy. In this study, we incorporated the dual-carbon strategy perspective into ecological product value (EPV) evaluation. The EPV is the sum of the final product and service value provided by regional ecosystems for human production and life. A significant uncertainty exists in evaluating the EPV. To bridge this gap, we explored the quantitative evaluation index system of EPV based on the dual-carbon perspective and conducted an empirical analysis relating to four subindexes (ecological protection, ecological products carbon neutral capacity transformation, ecological value, and ecological product value realization safeguard mechanism). The EPV in nine provinces of the Yellow River basin in 2020 was measured. The results showed that the total evaluation score of EPV realization in the Yellow River basin was relatively low, and the average scores of ecological product protection level, carbon neutrality capacity, value transformation level, and value realization guarantee mechanism were all at a low level. Overall, the protection level of ecological products and the guarantee mechanism to realize the EPV were relatively good. However, the carbon neutrality capacity and the value transformation level were relatively poor. From the spatial perspective, the value realization level of ecological products was roughly upstream region > downstream region > midstream region in the Yellow River basin. Finally, corresponding countermeasures and suggestions are put forward according to the comprehensive evaluation index of EPV realization and analysis of the four subindexes.

Responses and Resistance Capacity of Solanum Nigrum L. Mediated by Three Ecological Category Earthworms in Metal-[Cd-As-Cu-Pb]-Contaminated Soils of North China

Xiaoquan Mu Bo Li Wenju Liu Yuhui Qiao Caide Huang

Metal contamination occurs widely in China that impacts the safe production in agricultural land. Earthworms promote plant growth and metal accumulation from downground to aboveground. Few relevant studies have focused on the interactions between earthworms and Solanum nigrum L. to remediate metal-contaminated soils in North China. Hence, this study was conducted to investigate the effects of specific-species of earthworms (Eisenia fetida, Amynthas hupeiensis and Drawida gisti) on S. nigrum after 60 days of exposure to uncontaminated and [Cd-As-Cu-Pb]-contaminated soil (referred to as S0 and S1), respectively. In S1 soil, A. hupeiensis (anecic) had stronger effects on growth and metal accumulation in the organs (root, stem, and leaf) of S. nigrum than D. gisti (endogeic) and E. fetida (epigeic), which was attributed to their ecological category. The BAF values of S. nigrum were generally ranking in Cd>As>Cu>Pb; the BAFCd values were ranking in leaf>root>stem; BAFAs, BAFCu, and BAFPb were root>stem≈leaf. A. hupeiensis decreased the TF values of S. nigrum from the roots to the shoots. The co-effects of metal stress and earthworm activity on metal uptake by shoots suggested that A. hupeiensis increased the uptake of As, Cu, and Pb (by 56.3%, 51.5%, and 16.2%, p<0.05), but not Cd, which appeared to remain steady for prolonged durations. Alterations in the integrated biomarker response index version 2 (IBRv2) values demonstrated that A. hupeiensis (12.91) improved the resistance capacity (stimulated GSH, SnGS1, and SnCu-SOD) of S. nigrum under metal-containing conditions compared with E. fetida and D. gisti (IBRv2 were 9.61 and 9.11). This study might provide insights into the patterns of ‘soil-earthworm-plant system’ on improving remediation efficiency of S. nigrum, as the perspective of earthworm ecological niche partitioning.

The Photoperiod-Insensitive Allele Ppd-D1a Promotes Earlier Flowering in Rht12 Dwarf Plants of Bread Wheat

Frontiers in Plant Science (2018)

Liang Chen Yingying Du Qiumei Lu Chen Hua Ruishuang Meng

The gibberellin-responsive dwarfing gene Rht12 can significantly reduce plant height without changing seedling vigour and substantially increase ear fertility in bread wheat (Triticum aestivum. L). However, Rht12 delays heading date and anthesis date, which hinders its utilization in wheat improvement. To promote early flowering of the Rht12 dwarf plants, the photoperiod-insensitive allele Ppd-D1a was introduced through a cross between Jinmai47 (Ppd-D1a) and Karcagi (Rht12). The results showed that Ppd-D1a can rescue the delaying effect of Rht12 on flowering time and promote earlier flowering by 9.0 days (163.2°Cd) in the Rht12 dwarf plants by shortening the late reproduction phase. Plant height was reduced by Rht12 (43.2%) and Ppd-D1a (10.9%), achieving dwarf plants with higher lodging resistance. Ear fertility, like the grain number per spike, was significantly increased by Rht12 (21.3%), while it was reduced by Ppd-D1a (6.5%). However, thousand kernel weight was significantly reduced by Rht12 (12.9%), while was significantly increased by Ppd-D1a (16.9%). Finally, plant yield was increased by 16.4% and 8.2%, and harvest index was increased by 24.9% and 15.4% in the Rht12 dwarf lines and tall lines with Ppd-D1a, respectively. Clearly, there was additive interaction between Rht12 and Ppd-D1 and the introduction of Ppd-D1a advanced flowering time and improved yield traits of Rht12 dwarf plants, suggesting that the combination of Rht12 and Ppd-D1a would be conducive to the successful utilization of Rht12 in wheat breeding programmes.

Exploring resilience interactions and its driving forces in the land–water–biodiversity nexus at the watershed scale

Water Science & Technology Water Supply (2023)

Qingpu Li Zhengdong Zhang Cheng Li Luwen Wan Yang Yang

Abstract This study took the Meijiang River Basin, China, as an example, to simulate the resilience interactions of three key subsystems of land, water and biodiversity from 2000 to 2015, using a spatially explicit model. Twelve environmental variables were selected from natural, landscape pattern and socioeconomic dimensions to detect the dominant factors of system resilience interactions using a geographic detector model. We found that the resilience of water yield, soil retention and biodiversity were mainly influenced by landscape pattern factors. Additionally, terrain is a main driver of soil retention resilience, precipitation plays a critical role influencing water yield resilience variations and biodiversity resilience variations remain stable influenced by landscape pattern. Larger synergy and loss occurred between water yield resilience and biodiversity resilience compared with other pairs of resilience, while greater tradeoffs occurred between soil retention resilience and biodiversity resilience. The interactions among landscape pattern, precipitation, terrain and GDP were the main driving forces of land and water resilience interactions. The interactions of landscape pattern and terrain were the main driving forces of land and biodiversity resilience interactions. The interactions of landscape pattern, precipitation and GDP were the main driving forces of water and biodiversity resilience interactions. Our study implied that improving habitat connectivity could maximize benefits.
