宁东能源化工基地水土保持生态环境动态监测分析

Dynamic monitoring analysis of soil conservation and ecological environment of Ningdong Energy and Chemistry Industry Base

通过采用卫星遥感、地面定点和野外调查等监测技术手段,对宁东基地开发建设前(2000年)和开发建设初期(2007年)两个时段土地利用、植被盖度、土壤侵蚀、水土保持措施等水土保持生态环境影响因子分别进行监测。综合分析结果表明,宁东基地自2000年以来土地利用结构改善,植被覆盖呈好转趋势,虽然局部水土流失加重,但整体土壤侵蚀强度降低,整体生态环境处于好转状态。

Factors related to environmental impact such as land utilization, vegetative coverage, soil erosion as well as soil and water conservation measures, before （in 2000） and after （in 2007） the development of Ningdong Energy and Chemistry Industry Base, were monitored by means of remote sensing, land surface positioning and field investigation. The result shows that, since 2000, the intensity of soil erosion has been reduced and the overall environment in better state thanks to the improvement of land utilization pattern and increase of vegetative coverage, although severe erosion is existed in some areas.
