三峡库区高效生态农业发展方向与重点研究

, 2002
在三峡库区发展高效生态农业,是库区农村移民安置安稳、缓解人地矛盾、有效遏制生态环境恶化趋势的迫切需要,也是迎接加入WTO后的挑战、进行农业结构调整、确保三峡工程顺利建设和建设三峡生态经济区的迫切需要。论文提出了三峡库区高效生态农业发展的总体方向、主导产业与农业各行业发展的思路与重点。库区种植业发展重在压粮扩经,逐步压缩坡耕地粮食生产规模,提高名优特精经济作物的比重,大力发展高效优质生态农业,不求库区粮食自给平衡,但求库区生态平衡;林业突出优化改造经济林,加快建设生态林,大力发展香料林;畜牧业突出种草养畜,

三峡库区重庆段主要支流春季浮游植物调查

, 2006
三峡库区位于东经107°20’-111°01’、北纬30°31＇-30°20＇之间，流经重庆市和湖北省两个省级行政区。三峡水位提升至139m后，河面变宽，水深加大，水流明显减缓。库区主要污染源为工业污染源，其次按顺序排列为农田径流、生活污水、城市径流和船舶流动污染源，随着经济发展和人口增长，污染物排放增加，致使水体中营养物质浓度升高，库区水环境污染面临严峻形势 ...
