鲁山县是淮河重要支流——沙河的发源地,严重的水土流失不但使这里的水土资源日渐减少,生产条件日渐恶化,而且给下游人民的生命财产安全造成了巨大威胁。因此,加强这里的水土保持工作就显得特别迫切。为使水土保持工作更有效地进行,我们对该县的水土流失情况进行了实地调查、测量和室内航、卫片判读作图,对造成水土流失的不同原因进行了初步分析,提出了分区治理意见。 Lushan County is the birthplace of Shahe, an important tributary of the Huaihe River. Severe soil and water loss not only reduces the water and soil resources here, but also worsens the production conditions. It also poses a tremendous threat to the lives and property of downstream people. Therefore, to strengthen the soil and water conservation work here is particularly urgent. In order to carry out soil and water conservation work more effectively, we carried out on-the-spot investigation and measurement of soil and water loss and mapping of indoor air navigation and satellite dishes in the county to make a preliminary analysis of the different causes of water and soil loss and put forward a proposal of zoning control opinion.
