摘要:
官厅水库上游地区从1982年就被列入国家级水土保持重点治理区,国家不仅在水土流失治理方面进行大力投入,而且进行了多次土壤侵蚀遥感调查.各次土壤侵蚀遥感调查的成果在时间上形成序列,客观上为进行区域土壤侵蚀状况和生态环境变化的趋势动态分析提供了可能.在历年土壤侵蚀调查结果的基础上,进行了官厅水库上游永定河流域近20年来土壤侵蚀强度的时空变化分析,确定区域内水土流失强度在空间和等级的变化情况.
Abstract:
Since 1982 water and soil conservation strategies and measures have been taken in the upper basin of Guangting reservoir.Further investigations on regional soil erosion were carried out.The results came to be data series on temporary scales.Based on the existing regional investigation results the spatial and temporary changes of soil erosion intensity in recent 20 years in the upper basin of Guangting reservoir were analyzed.It can be concluded that soil erosion intensity was decreased in recent 20 years,but was not steady-going in this period.The environment in some areas is becoming better,and some areas represent different change in different temporary intervals.
