| 摘 要： | 湿地面积的大小制约着湿地功能的强弱,由于人类活动的干扰,扎龙湿地土地利用类型有明显变化。通过灰关联分析表明,在扎龙湿地主要土地利用类型中,对扎龙湿地面积影响最大的是居民用地和耕地面积,其次是盐碱地、草地面积的变化。在保证水资源量的前提下,控制湿地内的人口数量、限制耕地的开垦、发展替代产业,应该是保护扎龙湿地的有效措施。表1,参10。

| Abstract: | The area of wetland determines the functions of wetland.The land use of Zhalong wetland had changed obviously as a result of human activities.Through the gray relational analysis,we found that: Zhalong wetland area is mainly affected by the area changes of residents and cultivation,followed by those of saline soils,pasture area.Ensuring the amount of water resource,we should control the population,limit cultivation,and develop alternative industries,which will benefit to the protection of Zhalong wetland. |
