漳卫运河水系渔业环境现状的评价

漳卫运河水系的绝大部分河段已演变为季节性河流,河系沿岸缺乏植被,致使不能涵养水份和增加鱼类的自然饵料,故鱼的数量较少,尤其缺乏特殊的经济鱼类。建议充分利用已有的水库和蓄水坑塘,开展有计划养鱼;为保护大运河的自然环境,应减少人为污染,且积极植树种草,涵养水份及减少泥沙沉淤;发展洪期蓄水、旱期利用的多种形式工程,借以充分利用本河系的水资源。

The Fishery Environment Situation of Zhang-Wei Canal Scries Evaluation

The environment condition of Zhang-Wei Canal Series was studied in this paper. Results showed that most of Zhang He Wei He and the Grand Canal is seasonal river. Those riverside were lack of vegetation and the fishes are also less in these rivers. We suggest that the present rcseriors and ponds should be made better use. The plan to raise fish. For protect the natural environment of the canal, we should decrease pollution by person, active to plant trees and grasses, self-containment the member of water and decrease deposit of sandly mud.
