| 摘 要： | 地球表层系统最突出的景观标志是土地利用／土地覆被。人类通过土地利用改变天然土地覆被从而对脆弱敏感的岩溶水文系统产生了重大的影响。文章着重从农业土地利用出发综述了当前农业土地利用对岩溶水影响的研究。农业土地利用对岩溶地下水的影响主要围绕着水质和水量两个核心从以下几个方面展开：天然植被的清除，农业灌溉和排水，农业集约化所带来的化肥杀虫剂等的使用以及污染物质在岩溶含水层中的运移和影响。在此基础上作者从研究内容，理论方法和建立模型等方面都提出了自己的想法和建议。

| Abstract: | Land use and land cover is the most marked landscape on the earth. Land use and land cover has great influence on karst water by the integration of many natural factors, such as vegetable, soil, precipitation and geomorphology. The paper focuses on the advance of the influence to karst water by agricultural land use and land cover. The major influences to karst water by agricultural land use include clearing the grasses and forests for agricultural development, irrigating and recharging, using of agricultural chemical pesticide and fertilizer. In karst area the negative effects are strengthened because of the special structure in karst area. Based on the present domestic and abroad research, the paper proposes some new questions and advices on the field that should be strengthened further. |
