Study On Plant Landscape Design Under Extreme Environment In Zanggongma Village,Golog,Qinghai Province

With the continuous development of China’s economy,more and more rural areas are facing the process of modernization construction.However,blind construction and expansion are often accompanied by ecological and environmental problems,especially in ecologically fragile plateau areas.Blind urbanization can easily lead to ecological problems such as fragmentation,desertification,and salinization of plateau plant landscapes.The plant landscape in cold and arid plateau areas has always been a research hotspot for scholars in the industry,but most research focuses on the selection of plant types and pays less attention to plant design strategies.A good plant landscape should include multiple levels of "tree shrub grass".Therefore,this article will focus on the adaptability of local species and habitat conditions in cold and arid plateau areas.Based on the ecological learning ability of plants,a scientific and reasonable community structure and configuration model will be established,which has scientific guiding significance for the improvement of the surrounding environment landscape and the sustainable development of the ecosystem.1)This study analyzes and interprets the source,internal and surrounding conditions,upper planning conditions,and ecological environment conditions of the Guoluo Zanggongma Village project,clarifies the importance of plant landscape in extreme conditions for Guoluo Zanggongma Village,and proposes the plant landscape design issues of this study.2)The design of plant landscape in Gongma Village,Guoluo Tibetan Village,Gangca County was studied from the aspects of theory,norms,cases and field research,and the current plant landscape in the sample plot was evaluated using the analytic hierarchy process.In the investigation and study of vegetation prototype in Gangca County,107 species of plants were found.There are 7 species of trees,7 species of shrubs,and 93 species of herbs.By constructing a plant landscape evaluation system in Gongma Village,Guoluo Tibetan Autonomous Region,the natural native plant landscape and the current artificial green plant landscape in the surveyed sample plots are scored and evaluated,and those with good or bad results are selected for reference.3)Select the "habitat based plant landscape design method" for habitat creation and plant landscape design of the site.Firstly,divide the site habitat based on habitat factors that have a significant impact on the environment,such as "sunlight water soil wind".Then,targeted measures such as vertical design,soil improvement,and construction of wind barriers are taken to improve the habitat factors,Combining the improved site habitat with the dominant plant community combination pattern extracted from the investigation of local plant communities in the same habitat for plant landscape design.Through research,the following conclusions were drawn from this study:1)Summarize and sort out the methods for plant landscape design in Guoluo Zanggongma Village based on habitat creation,including two parts: habitat creation methods in cold and arid plateau areas and plant landscape design in cold and arid plateau areas,to make up for insufficient research focusing on the design of ground cover plant communities in high-altitude cold and arid areas.2)Extract plant landscape design methods in cold and arid plateau areas,and complete different types of plant community combinations based on plant landscape spatial types combined with site habitat conditions.3)From the perspective of plant landscape design,three structural patterns of tree grass plant communities,three matching patterns of ground cover plant communities,and three mixed grass species combinations,as well as the structural patterns of waterfront wet plant communities,were extracted.
