牡丹江流域生态环境现状及保护对策

Present Situation of Ecological Environment and Protection Countermeasures in Mudan River Basin

"十一五"期间,牡丹江市土地没有退化,森里和草原资源丰富。牡丹江干流水生态环境良好,水生生物优势种明显。牡丹江市辖区河段果树场-牛场村,生物多样性高,水土保持较好。牛场村-温春镇兴隆河段,水生生物多样性已呈减少趋势,陆生生物多样性一般,土壤侵蚀中等。牡丹江市区河段,水生生物多样性差,陆生生物很少,水土流失现象严重。结合牡丹江流域生态环境特点,提出适宜的生态保护对策。

During the period of the Eleventh Five-Year Plan,soils hadn＇t been degraded,the resources of forest and grassland were rich in Mudan River basin.The water quality is good and dominant species of aquatic organisms are significant in the main stream of Mudan River.From Guoshu field to Niuchang village,there are high biodiversity and well soil and water conservation.From Niuchang village to Wenchun town,aquatic biodiversity has decreased and continental biodiversity is common.In the area of Mudanjiang city,aquatic biodiversity is poor,the quantity of continental biology is few,and soil erosion is serious.Considering to the characters of ecological environment,we propose some ecological protection countermeasures.
