- Title:
- Mapping the Intensity Chart of Soil Erosion With the Data From Remote Sensing Investigation in Huangjia-Ercha Small Watershed
- 摘要:
- 本文根据土壤侵蚀分类原则，在1：10000彩红外航片上获取影像的土壤侵蚀判读标志，应用遥感技术调查编制了小流域土壤侵蚀强度图。实践证明，该方法具有快速、准确和省工特点，可直观反映水土流失现状、侵蚀类型的分布面积大小和特征，评价土壤侵蚀强度，为流域综合治理和开发利用提供依据。分析结果同时表明：西吉试验区经过6年的综合治理，土壤侵蚀强度已由治理前的强度侵蚀类型下降为微度侵蚀类型。
- Abstract:
- Based on the principles of classifing soil erosion,the mark of the ‘Read with film’was obtained by using 1:10 000 colour infrared aerial photo. By the method of remote sensing technology, we investigated and made a map of soil erosion intensity in Huangjia-Ercha small watershed. It was probed in practice that this method is such a method with the charicteristics of quickness, accuracy and labour-saving, which can directly reflect the present situation of soil erosion, areas of various erosion type and its distribution, and be used to evaluated the soil erosion intensity. All these above provide a scientific basis for the comprehensive control of soil erosion and development of small watershed. It was showed out clearly in the section of result and analysis that after 6 year’s comprehensive harness, the soil erosion intensity in Xiji Experiment and Examplary Area has been changed to be a weak one from intensive type before harness.
