辽宁土壤侵蚀管理的时空变化及其防治方略
- Title:
- The Time and Space Changes of Soil Erode Management and Control Strategies in Liaoning Province
- Keywords:
- soil erosion; time and space change; control strategy
- 摘要:
- 通过10年间两次遥感普查的数据分析，阐述了10年间土壤侵蚀从面积上和程度上都呈减少的变化趋势。土壤侵蚀的空间变化提醒人们注意，星罗棋布的点源侵蚀正由丘陵向低山蔓延。针对全省土壤侵蚀的变化结果和今后面临的任务提出了预防与治理的方向和策略。
- Abstract:
- Based on the data analysis obtained for two telemetering surveys in ten years,the soil erosion in Liaoning province has been taking reduce trendy on the area and extent. However, the soil star-point erosion is being extended from hillyland to low mountain region. These changes showed direction and strategy for the province soil harness.
