摘 要 ：以梅子垭村的一个小集水区及与之相邻的梅子垭水库为研究对象 ,根据降雨过程中集水区产生的径流输入及在水库库湾不同取样点上所取水样的分析结果 ,初步建立了 P元素在库湾中的一维 A.B.卡拉乌舍夫扩散模型 ,并对水库的水质状况与对应小流域的植被类型的特征之间的关系进行了分析。研究结果表明 ,水库水质与毗邻陆地生态系统的状况密切相关 ,以经济效益为主要目的的对陆地生态系统的过度开发将导致水库水质恶化 ;因此有必要将水陆生态系统综合考虑 ,以达到水陆复合生态系统的最大生态及经济效益。

Abstract:Nutrition condition of waters is an important and synthetical expression of various nutrients and the relationship between these nutrients and different kinds of organisms in aquatic ecosystems. Water nutrition condition is also one of the most important factors that influence the utilization of water resources. It is obviously significant for guiding the decision policy on the utilization of water resources to study water nutrition condition. Aquatic ecosystems are easy to be suffered from the influences ...
