人为影响下古尔班通古特沙漠小尺度生态环境变化

随着沙漠中油气资源勘探开发、公路建设和重大工程相继实施 ,对生态环境的人为影响日益加深。本文以重大工程实验点为例 ,通过研究对比工程影响区内人工沙垄和自然沙垄的砂质新成土理化性状和植被群落特征 ,指出了沙漠生态环境在人为干扰下发生的一系列变化 ,以及受损生态环境在人们采取积极补救措施的情况下所具有的自然修复能力

Eco-environmental Change of the Gurbantunggut Desert in a Small-scale Under the Human Impact

The Gurbantunggut Desert of Xinjiang is a temperate one; its eco-environment is very fragile. With the exploitation and development of the oil-gas resources, the implementation of the desert highway and water conservancy construction in the Gurbantunggut Desert, the impact of human activities on the eco-environment has increasingly been sharpened.In this paper, taking the third test sites of engineering in the Jungger Basin as a case, by comparing the physical-chemical properties and vegetation community characteristics of artificial longitudinal dunes with natural longitudinal dunes, points out that the eco-environment of the desert changed under human disturbance, such as the physical-chemical properties became worse and the vegetation was remarkably damaged. Meanwhile, the paper still shows that when people adopt the active measurements the disturbed eco-environment has a capacity of natural rehabilitation.
