太湖流域水环境演变与人类活动耦合关系

太湖流域水环境与人类活动之间存在相互制约、相互作用的关系。从 2 0世纪 6 0年代起 ,随着经济的发展、工业化与城市化进程的加速 ,流域水环境不断恶化 ,具有表征意义的太湖水体的TP ,TN ,COD浓度不断上升。本文把环境演变的人文驱动因素归纳为人口发展、经济发展、城市化、土地利用等 ,将其与太湖流域水环境耦合 ,得出探讨性结论 :太湖流域人类活动与水环境之间的互动关系大致经历了干预、干预—弱制约、干预—制约、干预—强制约四个阶段 ,每个阶段对应着不同的人类活动特征。流域水环境恶化经历了几十年 ,而水环境修复则需要人类更长时期的共同努力

PRELIMINARY STUDY ON THE COINCIDENT RELATIONSHIP BETWEEN WATER ENVIRONMENT AND HUMAN ACTIVITY IN TAIHU LAKE BASIN

The relationship between water environment and human activity has been interactive in Taihu Lake basin.With the development of economy,industrialization and urbanization,the water environment has become worse ever since 1960's,and the values of indicatives for water quality such as TN,TP and COD have been increasing in the basin.In this paper,four human factors related with water environment were indentified to be:population increase,economy development,urbanization and land use.The relationship between water environment and human activity has undergone four stages,each having different characteristics.Water environment has been deteriorated for forty years in Taihu Lake basin,but it may take much longer to restore the water environment complete.
