Study On The Habitat Construction And Plant Community Design In The Desert Steppe Area Of The Eastern Foot Of Helan

Helan Mountain is a special geographical location,which is the boundary between arid and semi-arid areas in Northwest China.Due to the influence of natural factors such as lack of precipitation and poor climate conditions,the ecological environment is relatively poor.In addition,human interference and destruction make the damaged ecological environment more vulnerable.It also brings a series of ecological environment problems,such as soil erosion,vegetation degradation,land desertification,biodiversity reduction and so on.With in-depth understanding of the "ecological" environment construction,and through various research and comparison,and drawing lessons from successful cases at home and abroad,a proposal of "approaching nature and imitation of nature" is established.This idea is based on the implementation of President Xi Jinping's ecological civilization and the basic principles of methodology.From the point of Helan's Shandong foothill,the plan is respecting the diversity of natural ecology.From the perspective of sexual law,the transformation of "ecological" green construction takes place,and plays the role of experimental demonstration.This paper focuses on the study of habitat construction and plant community design in the desert steppe area of the eastern foot of Helan,in order to solve the problem of vegetation restoration.Based on the definition of habitat in ecology,this paper systematicallycombs and analyzes the terrain,water,soil and other habitat elements in the desert steppe area of the eastern foot of Helan Mountain,and designs and studies the composition of plant community after meeting the conditions of habitat construction.Let the plant community meet the requirements and conditions of basic functions,but also meet the aesthetic needs.Through the summary of the study on this area,it can be used as a reference for similar site design research in the future.
