本文在分析通双小流域治理情况的基础上,应用灰色系统理论对粮食总产量及其影响因素作了定量化的研究,认为粮食总产量的年度变化主要受田间蓄水量、土壤流失量、径流深和降雨量四个因子的影响,其中田间蓄水量为主要因子。据此,提出了有效防治水土流失和提高粮食总产量,改善生态环境的意见.
Based on the analysis of the governance of the Shuang-small watershed, this paper uses the gray system theory to make a quantitative study on the total grain output and its influencing factors, and considers that the annual changes of the total grain output are mainly affected by the storage capacity of the field, the amount of soil loss, Runoff depth and rainfall four factors, of which the field water storage as the main factor. Accordingly, put forward the opinions of preventing and controlling soil and water loss effectively and raising the total output of grain and improving the ecological environment.
