摘 要:本文从伊懋可等人提出的有关"水利系统与自然环境并不总是和谐共生的关系"等论点出发,以历史时期大别山区灌溉水利开发进程与生态环境变迁的互动关系为考察对象,申述水利系统过度开发可能引发的负面环境效应问题。可以发现,在南方山地环境下,特别是在山区腹地河流上游的垦殖过程中,灌溉水利活动的参与程度与小流域整体生态功能之间往往呈现逆向互动关系。由是指出,水利既是不可替代的农业命脉,同时也有其自身的价值限度与利用边界。Mark Elvin has once proposed that "Water-control systems are where society and economy meet the environment in a relationship that is more often than not adversarial". Based on his argument, this paper investigates the interactive relations of environmental change in the development process of irrigation water conservancy around Dabie Mountain Area during historical period. The article demonstrates the possible negative environmental influence caused by overexploitation of water conservancy systems. The interaction between irrigation water development activities and small watershed's overall ecological function often rendered as reverse in the southern mountain environment. Consequently, the paper indicates that water conservancy is an irreplaceable lifeline of agriculture, but also has its own value limits and utilization boundaries.
