Quantitative Study on Morphological Change Characteristics of Tonle Sap Lake Based on DEM

Open Journal of Modern Hydrology (2023)

Yan Huang Changwen Li Yifei Tian Wu Liu Nan Zhang

Lake is an important part of the natural ecosystem, and its morphological characteristics reflect the capacity of lake regulation and storage, the strength of material migration, and the characteristics of shoreline development. In most existing studies, remote sensing images are used to quantify the morphological characteristics of lakes. However, the extraction accuracy of lake water is greatly affected by cloud cover and vegetation cover, and the inversion accuracy of lake elevation data is poor, which cannot accurately describe the response relationship of lake landscape morphology with water level change. Therefore, this paper takes Tonle Sap Lake as the research object, which is the largest natural freshwater lake in Southeast Asia. DEM is constructed based on high-resolution measured topographic data, and morphological indicators such as lake area, lake shoreline length, perimeter area ratio, longest axis length, maximum width, shoreline development index, lake shape complexity, compactness ratio and form ratio are adopted to researching the evolution law of high water overflows and low water outbursts quantitatively, and clarifying the variation characteristics of landscape morphology with water level gradient in Tonle Sap Lake. The research results have important theoretical significance for the scientific utilization of Tonle Sap Lake water resources and the protection of the lake ecosystem.

Charity and Business Guild in Xinjiang

Journal of Lanzhou University (2011)

Changwen Li

Charity is the main instrument for community management and business guild development as well as a need for local government agencies.The business guilds in Xinjiang,having been evolving for many years,are characterised by their own special features and meanwhile suffering from special problems.The cultural and social pluralization in this area requires expansion of charity ranges,improvement of the expertise of the charity personnel, reinforcement of the sense of social obligations and regulation of charity acts.

Effects of Different Microorganisms on the Fermentative Process of Pu-erh Tea

Chaye kexue (2012)

Changwen Li

In order to explain the effects and mechanisms of microorganisms on the fermentative process of Pu-erh tea,For the purpose of providing the theory and data support for industrialized fermentation of Pu-erh tea,the monoxenie fermentation under individual microorganism and mixed fermentation experiments of Pu-erh tea were carried out.The experiments discovered the effects of different microorganisms by tracing the influences of different strains to sense quality and physics and chemistry index in the fermentative process of Pu-erh tea.The results showed that in the fermentative process of Pu-erh tea,the color of tea became to hepatic from green,the bitter sense of tea soup taperred,the tea soup was red and bright.The contents of tea polyphenol and water extract were decreased,while the contents of theabrownin and caffeine were increased.Furthermore,the influence of fungi to these components was largest,yeast was less than fungi,bacteria was least.Mixed fermentation tea possessed ripe tea quality when fermented 20 d.Forementioned results proved that fermenting Pu-erh tea with reasonable matching can not only shorten fermentative time,but also preferably control and benchmarking the fermentative trend and result of Pu-erh tea.

Can safe and radical resection of all types of parasagittal meningiomas be achievable? —the introduction of a simplified surgical strategy

Neurological Research (2020)

Nan Zhang Tao Yang Farrukh Hameed Xiang Zhang Yang Yao

Background: Surgery of parasagittal meningiomas (PSMs) is still technically challenging, for the balance between radical resection and preservation of venous circulation. In this article, we'd systemically introduce the technical nuances of a simplified strategy for radical resection of all types of PSMs. All the cases were operated by one single neurosurgeon from a single institution.Methods: Clinical charts of patients with PSMs between 2014 and 2020were retrospectively reviewed. A simplified classification method was adopted, which was based on the relationship between the tumor and superior sagittal sinus (SSS). Surgery aiming at radical resection and venous flow preservation was performed. Only in case of total occlusion of SSS, we performed tumor resection without reconstruction of the venous sinus.Results: Clinical data obtained in 55 consecutive patients (47 primary and 8 recurrent cases) were analyzed, among which 20 were with patent sinus, 27 were with partially occluded sinus and 8 were with completely occluded sinus. Forty-two (76.4%) and 13 patients (23.6%) had the same and improved functional status as compared to that of pre-operation, respectively. Four patients (7.3%) experienced transient neurological deterioration but improved to the normal level in the long-term follow-up. All patients achieved Simpson I/II radical resection. No patients suffered from post-operative recurrence in the follow-up duration of 27.05 ± 19.55 (2-91) months.Conclusion: Radical and safe resection of all types of PSMs is achievable and not difficult if the simplified surgical strategy mentioned in the article is adopted, no matter to which extent the sinus is invaded.

Sensitivity Analysis of Rock-Fill Dam Break Flood on Different Dam Break Durations

Open Journal of Safety Science and Technology (2021)

Changwen Li Huabin Gao Zhaoming Xu Huang Yan

The dam break pattern of rock-fill dams is normally gradual failure. This kind of dam failure is caused by seepage piping or overtopping, in which dam crest overflow is more common. The dam breach expansion process shall depend comprehensively on the structure pattern, material property of dam, and damsite cross sectional topography. And the break duration has a significant impact on the magnitude of break flood and the counter-measures for excess-standard flood. Take the Karot Hydropower Project constructed on the Jhelum River in Pakistan as an example, the dam break mathematical model is set up to analyze the sensitivity of damsite discharge process, downstream highest flood water surface profile and flood peak appearance time to dam break duration. The results show that: with the increase of dam break duration, damsite peak discharge is decreased sharply, flood peak appearance time extends, on-way highest water levels below Karot dam are lowered significantly, and some settlement places below Karot dam can avoid being inundated until the break duration reaches a critical value. If encountering probable maximum flood, the dam break occurs when the reservoir water level reaches dam top EL, some measures can be taken to extend the break duration, so as to effectively reduce the loss of downstream flood. The research results will help to understand the relationship mechanism between rock-fill dam break flood and break duration and provide a scientific basis or some solutions for optimization design of dam and counter-measures of dam break flood.
