Research On The Ecological Environment Status And Optimization Strategy Of Urban Green Space Landscape In Beijing,Shijingshan District

In the complex complex system of cities,urban green space is the only carrier with ecological regulation ability.Its role of ecological functions and ecological benefits are irreplaceable.In the present state of rapid urbanization,the amount of land used in urban areas is very tight.This makes the improvement of urban greenland ecosystem not only limited to the increase in the rate of greening and greening,instead,it needs to be achieved through the various space values of the green space itself,that is,by optimizing the rational spatial layout and structure of each green space.Therefore,giving full play to the ecological capacity of urban green space and coordinating the relationship between the development of modem cities and the ecological environment is an important issue for Shijingshan District in Beijing to meet the national green development demonstration area.Although a large amount of research and practice has been conducted to evaluate the landscape ecological environment of urban green space in Shijingshan District,there is no quantitative measurement and evaluation of the plant structure and the feeling of plant space created within the green space.This has become a problem that needs to be solved urgently in the construction of urban greenland landscape ecological environment in Shijingshan District where sustainable development is the goal.According to the statistics of the "Beijing Urban Landscape Afforestation Survey Data Collection"(2014 edition),Beijing Shijingshan District is the city with the highest green area rate and per capita green area in Chengliu District of the city.However,in the last ten years,the amount of urban green space in Shijingshan District has remained basically stable.Therefore,in the future,while maintaining the stability of the current status of green space,the detailed study of the landscape space created by urban plants within the urban green space of Shijingshan District and the improvement of the ecological value created by it will become one of the ways to optimize the green space ecosystem in Shijingshan District of Beijing.In the first two chapters of this paper,the background information of the urban landscape ecological environment,relevant concepts,and the development goals and current status planning of the Beijing Shijingshan District were sorted out.The current academic research status at home and abroad is summarized and summarized,and the specific contents and methods of each research are summarized.The third chapter analyzes the urban green space of Shijingshan District from the macroscopic perspective,combs all the urban green space in Shijingshan District,and classifies,statistics and analyzes it.Afterwards,using TM remote sensing and ArcGIS software to calculate,analyze and compare the three-dimensional green volume of Shijingshan District as a whole.From the macro level,the urban green space and its distribution in Shijingshan District were evaluated.Chapter 4 evaluates and analyzes the landscape ecological environment of urban green space in Shijingshan District from the meso-level perspective,and analyzes the diversity of the plant landscape and the suitability of the microclimate of the garden.Quantitative statistics were made on the landscape diversity created by plant landscapes and the suitability of microclimates,and then statistically summarized by using the comparison of urban green spaces.Based on the above research on the current status of urban greenland landscape ecological environment in Shijingshan District of Beijing,and on the basis of comparative analysis of the above research data and advanced cases,the fifth chapter proposes the corresponding optimization principles of urban greenland landscape ecological environment in Shijingshan District.At the same time,using Envi-met to simulate the corresponding plant landscape to form an effective data result,so as to more accurately put forward the corresponding optimization content and methods.Finally,in the sixth chapter,we sum up the optimization strategies that are conducive to the construction and optimization of the landscape ecological environment of urban green space in Beijing Shijingshan District.The research of this paper can provide corresponding reference for the future construction and optimization of urban greenland landscape ecological environment in Shijingshan District.
