- Title:
- Predicting the Trend of the Soil and Water Loss of China in 2000, and the Countermeasures Controlling It
- 摘要:
- 目前我国水土流失分布面积尚无准确的数字，土壤侵蚀强度分级还缺少统一的标准，而河流输沙量方面的观测资料比较系统。由于河流输沙量与流域内的水土流失成正相关，所以，我们根据河流输沙量的变化情况，来进行水土流失趋势预测。在多雨年和少雨年，年输沙量相差悬殊，单纯根据年输沙量的大小，很难准确判断出流域内水土流失的变化趋势。为此，我们建立了河流输沙量与流域内影响水土流失各主要因素之间的相关方程，用以进行水土流失趋势预测。根据近年来水土保持工作快速发展的形势预测出，从现在起到2000年，我国水土流失有减弱的趋势，并提出水土保持对策。
- Abstract:
- At present,there is not yet a exact figure of the range of soil and water loss distributing in China,and still it is lack in the unified standard of grading for soil erosion intensity.However,the date of sediment load observed are rather systematic.Considering the sediment load is positively correlated to the soil and water loss in a watershed, therefore,it is possible that we can predict the trend of the soil and water loss according to the varation of the sediment load.There is a great disparity in the amount of annual sediment load between rainy year and rare rain year.But it is very difficult to distinguish exactly the trend of soil and water loss in the watershed simply based on the annual sediment load.In order to predict the trend of the soil and water loss, the interrelated equation has been developed for the sediment load and the main factors affecting the soil erosion in the watershed.According to the excellent developing circumstances of soil and water conservation in the recent years,it can be predicted that from now to 2000,the soil and water loss in our country will show a tendency weaken.The countermeasures have been put forword for the soil and water conservation.
