基塘系统:现状、问题与前景

种养结合，水陆交互作用显著的基塘系统，具备多种生态经济功能，是水网地欧重要的农业生态系统模式和生态景观，最近十多年不断加重的环境污染和基塘自身种养比较失调，使其萎缩和退化现象十分突出，文章就目前基塘系统主要研究内容与方法进行了分析展望，认为要用可持续发展的观点指导基唐系统经营。

The integrated Dike-pond systems : its new developments and ecological problems

The Integrated dike-pond system, which has been practiced in Chinese wetland for centuries, has an obvious land-water interaction and remarkable eco-economical benefits. Since the late 1980s, serious environmental pollution and ecological degradation have triggered far-reaching alterations in the integrated dike-pond system structure, spatial patterns, and species diversity. Following the shift of mulberry in dick and the decline in the raising of traditional Chinese carps in ponds , the development of a more sophisticated and intensive monoculture has emerged and the integrated dike-pond system atrophy and degradation have been occurred. Environmental pollution, market-oriented, high-valued monocultural system focusing primarily on expanding pond surface to raise production value per (pond) unit tend to threaten sustainability of the integrated dike-pond system as well as the wetland region. A series of ecological safe model should be developed. A countermeasure was given on how to deal with dike-pond problem.
