水土保持综合治理动态的航空遥感评价

以不同时期大比例尺遥感信息源为依据,对区域水土保持综合治理进行科学地、客观地评价,并以图的形式从定性、定量、定位诸方面表示出综合治理措施的空间分布、质量水平、生态和经济效益。然后把两期的综合治理评价图进行叠合比较,编制新的综合治理评价动态图,研究综合治理评价的动态变化,并可以直观地显示出今后需要加强治理的地块以及治理方向。

Dynamic Evaluation of Integrated Measures for Soil and Water Conservation by Remote Aerial Reconnaissance

Based on the information of Remote sensing on the large scale from different periods. The regional integrated measures for soil and water conservation were objectively and scientificall evaluted. The spatial distribution the quality level and the economic-ecological benefits of integrated measures were illustrated qualitatively, and orientationally by mapping. Then, the evaluation maps of integrated measures from the two periods were comparced, so that a new evaluation map of integrated measures was developed to study the dynamic change of soil and water conservation. Moreover, the map can give more informatiol controlling and research direction aresuch as area where the control should be strengthered suggested, and development direction for soil ero sion control
