摘　　要：应用TM遥感影像,提取土地利用和土壤侵蚀的相关信息。采用叠加分析的方法,对黑龙江省克山县1995-2000年的土地利用变化和土壤侵蚀变化的关系进行了分析。结果表明:黑龙江省克山县土地利用的变化不利于水土保持、土壤侵蚀面积的减少以及土壤侵蚀强度的降低,影响土壤侵蚀的主要土地利用变化发生在微丘平原区旱地。Information on land use and soil erosion was extracted from TM remote sense images. The relation between land use change and soil erosion change was explored by overlapping the respective map layers. Results show that land use change in county of Keshan, Heilongjiang Province is unfavorable for soil and water conservation. The main land use change enhancing soil and water conservation occurs on the dry upland. Changes within dry land areas, i. e. the conversion of dry land to terrace, are the most effective for preventing soil erosion.
