扎龙湿地土地利用类型评价研究

Assessment and Research on Land-Use in the Zhalong Wetland

扎龙湿地属于典型的芦苇沼泽湿地,由于扎龙湿地水环境的变化,扎龙湿地土地利用类型的变化为:耕地、居民地、盐碱地总体上略呈增加趋势,草地呈减少趋势,湖泊和水库、明水沼泽、芦苇沼泽等湿地面积变化与来水量的丰枯变化相关,明水沼泽和芦苇沼泽的变化趋势呈反相关。土地利用类型对湿地面积的影响程度最大的是居民地面积,其次是耕地、盐碱地、草地面积的变化。

The Zhalong Wetland is a typical reed swamp. With the change of water condition there, land-use has changed. Farmland, residential area and salina have been increasing while the grassland is reducing. The wetland areas, such as lakes, reservoirs, swamp with open water and the reed swamp, are correlated with water amount variety. The swamp with open water is adverse correlated with reed swamp. Comparing with the change of farmland, salina and grassland, residentialland-use has the most impact on the wetland area.
