Gap characteristics in the natural forests of Pinus yunnanensis alone the Jinshajiang Basin in Yunnan Province

Zhejiang Linxueyuan xuebao (2005)

Peng Jian-song Chai Yong Meng Guang-tao Fang Xiang-jing Guixiang Li

The gap characteristics and natural disturbance regimes of 45 gaps in the natural forests of Pinus yunnanensis were studied , in Baimahe Forest Farm and Xiangshuihe Forest Farm of Yongren County , in Yunnan Province .The results showed that these gaps were elliptic in horizontal form .The average area of expand gap (EG) and canopy gap (CG)were 469.42 m2 and 181.90 m2 respectively , the area percentage of both in the forest landscape were 28.23 % and 10.49 % respectively , and annual natural disturbance frequency of both were 0.672 1 % and 0.247 9 % respectively .So the return interval of the gap was gotten , about 400.48 a .These gaps mostly formed 40 a ago , and made by 1 to 3 gap makers (mainly by one).The diameter of gapmakers was mainly from 30 to 50 cm, and the height of which was mainly from 20 to 30 m .The manners of gap formation in the percentage order from high to low were :uprooting (33.7 %), breakage at trunk base (27.9 %), breakage on trunk (18.6 %), standing die (17.4 %), and breakage on branch (2.4 %).The combination of the different manners can be found often .Finally , based on the theory of gap dynamics , some suggestions on the natural forest of Pinus yunnanensis management were provided .[ Ch , 5 tab .10 ref .]

Soil Condition Analysis and Application Technology of Forestation at Sides of Chenghai Lake

Xibu linye kexue (2006)

Guixiang Li Fang Xiang-jing Meng Guang-tao Zhang Zheng-hai Rui Ai-min

Through analyzing the soil conditions of lakesides of Chenghai Lake,aiming at the difficulty in forestation,some technical measures were proposed on the basis of experimental study.The results of analysis indicated that the sides of Chenghai Lake were mostly covered with loose sediment,the percentage of stone and gravel was high as 79.31 % or above,the soil water penetrability was big,not good for both water and fertilizer preservation.In forestation experiments,using quality big size container seedling,soil replacement,big planting pit,seep-hose irrigation system in dry season,good forestation effect was achieved.

Characteristics of Alnus cremastogyne plantation community and its biomass in central Yunnan Plateau

Zhejiang Linxueyuan xuebao (2006)

Guixiang Li Meng Guang-tao Fang Xiang-jing Lang NanJun Yuan Chun-ming

A study of the Alnus cremastogyne plantation showed that it was characterized by fast-growing , flourishing root system , quick undergrowth restoration , higher biodiversity , soil improving and water holding capacity .The biomass of tree organs were in order trunk root branch bark leaf .The roots in the soil layer of 0 -40cm accounted for 96.14 %of the total roots .The biomass in the arbor layerwas the largest , accounting for 84.93 % of the total biomass of the plantation .The biomass of leaf litter layer , herbage layer and shrub layer were less than the arbor layer .Finally regression models of the biomass of different Alnus cremastogyne organs were established to provide the reference for the management of the Alnus cremastogyne plantation .

Research Progress of Artificial Forest in the Remediation of Heavy Metal Contaminated Soils

IOP Conference Series Earth and Environmental Science (2017)

MA Jiafang Meng Guang-tao He LiPing LI Gui-xiang

(1) Remediation of soil contaminated by heavy metals has become a hot topic in the world, and phytoremediation technology is the most widely used. (2) In addition to traditional economic benefits, ecological benefits of artificial forest have been more and more important, which are very helpful to soil polluted with heavy metals in the environment. (3) The characteristics of heavy metal pollution of soil and plantations of repair mechanism have been reviewed, and the current mining areas, wetlands, urban plantations on heavy metal elements have enriched the research results. The purpose is to find a new path for governance of heavy metal soil pollution.

Tree species richness and abundance in a four-ha plot in a mid-montane humid evergreen broad-leaved forest in Gaoligong Mountains of Yunnan province, China

Journal of Food Agriculture & Environment (2014)

Yong Chai Meng Guang-tao Zhu Hua LI Gui-xiang Yuan Chun-ming

We censused all free-standing trees with diameter at breast height (dbh) ≥ 1 cm in a four-ha plot in a mid-montane humid evergreen broad-leaved forest in Gaoligong Mountains, Southwest China. A total of 10,546 freestanding trees with dbh ≥ 1 cm were recorded, and all individuals, including 95 species from 64 genera and 35 families were identified. Nine of 95 species had more than 300 individuals, with 4,472 in total. Eleven species had only one individual in the four-ha plot. Symplocos ramosissima (Symplocaceae), the most abundant species (837 stems), and Gordonia longicarpa (Theaceae), the species with the largest basal area (13.05 m 2 ), were most dominant in the plot. Compared with other dynamic plots in China, the plot had intermediate levels of species richness, stem density, and basal area, but the proportion of rare species and the maximum importance value were lowest. The species abundance pattern models changed from a logarithmic series model (for the trees with dhb ≥ 1 cm) to a logarithmic normal model (for the trees with dbh ≥ 10 cm), and to both geometric series model and logarithmic normal model (for the trees with dbh ≥ 20 cm), reflecting the differences in community characteristics among trees with different size.

Study on Niche of Betula luminifera Population and Its Main Associated Tree Species in Fuyuan,Yunnan

Nanjing Linye Daxue xuebao (2006)

Meng Guang-tao Chai Yong Fang Xiang-jing

Using Levins and Shannon-Wiener niche breadth index,the niche of Betula luminifera population and its main associated tree species in Fuyuan County,Yunnan was studied.The results showed that B.luminifera had the biggest niche breadth.The niche breadth of Cunninghamia lanceolata,Pinus armandi ranks second.The niche breadth of other associated tree species was smallest.It indicates that B.luminifera has extensive adaptation to environment and it is the dominant species in the community.The niche proportional similarity between B.luminifera and C.lanceolata,P.armandi was larger,showing that B.luminifera and C.lanceolata,P.armandi had greater resource-sharing degree.But the niche proportional similarity between B.luminifera and most of other associated tree species were small.The niche overlap between most of tree species in B.luminifera community were smaller,which indicated a higher niche polarization of main tree species and a weaker competition in B.luminifera community.

Study on Runoff and Soil Erosion of Man-Made Plant Community in Mountain of Central Yunnan Plateau

Meng Guang-tao Yuan Chun-ming

According to the 5 years' observation,the study on the precipitation and runoff of man-made plant community in central Yunnan Plateau was conducted,and some results are as follows: the season distribution of precipitation in the area is uneven,the rainfall of wet season account for 86.64% of the year totals,the precipitation is mainly brought by rainfall with more than 10mm,and most of the rainfall intensities are less than 5 mm/h.Compared to wasteland,the forest land have a notable effect of soil and water conservation.In trial watershed,the runoff has a highly correlation with precipitation,and soil erosion is determined by runoff primarily,following the precipitation.
