| 摘 要： | 降雨径流是引起土壤侵蚀的主要动力,因此准确预测不同下垫面条件下的径流量是进行土壤侵蚀预报和水土流失治理的关键.SCS-CN方法是目前国际上预测无径流观测资料地区降水产流的主要模型.利用黄土高原地区6个试验小区的153场径流试验资料,选取3种具有代表性的土地利用方式:谷子、苜蓿和高粱,对SCS-CN方法在黄土高原的适应性进行了初步检验,优化出了适应黄土高原地区3种土地利用方式的模型参数.结果表明,优化后的模型参数对降雨径流的预测精度明显优于标准SCS-CN法;优化后的λ值为0.01,优化的谷子、苜蓿和高粱地CN2 值分别是74,74,72.

| Abstract: | The compound water resource system was regarded as the subjectinvestigated. The coupling relationship between water resource utilization and eco-environmentwas ascertained. Sustainable water resource utilization was found to be the effective measure of harmonizing water resources and eco-environment. An evaluation system including the three levels of target,rule,and index was setup according to metric demands of sustainable water resource utilization. The principles of erecting evaluation system were established. Indexes were filtrated by frequency analysis method,theoretical analysis method,and expertconsultation method. Weightof each indicator was determined by expertconsultation method and Improved Analysis Hierarchy Process (IAHP) and thus,the subjective deviation was reduced. The weighted values of indicators were finally analyzed. Results indicate thatthe essential attributes of water resources are the most important aspectof judging the sustainable utilization degree of water resources,whereas the influence of fragile eco-environ-mentranks second. |
