鄱阳湖自然环境及现状

NATURAL ENVIRONMENT AND PRESENT STATUS OF POYANG LAKE

鄱阳湖,是我国目前最大的淡水湖泊,是我国重要商品根基地之一。本文叙述了鄱阳湖的自然环境及现状。由于鄱阳湖所处的地理位置和地形,所以具有丰富的光、热、水、风能气候资源,为农业生产提供了优越的气候条件;水资源丰沛,地表水年总量达1457亿立方米;洪水位受五河、长江双重影响;洲滩资源有开发利用价值;有珍禽鹤类群;鄱阳湖水质目前是较好的,但也受到污染。湖区环境整治主要是水土流失、水质污染、洪涝灾害等。整治要远近结合、综合治理、驯服五河、人工控湖。使鄱阳湖农、林、牧、副、渔各业均衡发展。
