|
摘要
以大兴安岭第二次湿地资源调查数据为依据,对大兴安岭东部林区各类湿地进行了统计及特征分析。结果显示:大兴安岭东部林区主要分为黑龙江干流、呼玛河和嫩江源3个湿地区。湿地总面积153.08×10~4hm~2,占全区总面积的18.33%。湿地类型主要以沼泽湿地为主,面积147.11×10~4hm~2;其次为河流湿地,面积5.86×10~4hm~2;永久性淡水湖泊湿地和人工湿地数量较少,面积分别为0.05×10~4hm~2和0.06×10~4hm~2。10个林业局湿地分布面积125.79×10~4hm~2,6个地方林场湿地面积7.1×10~4hm~2,8个保护区湿地面积20.17×10~4hm~2。
Based on the data of the second wetland resource survey in Daxing'anling, the statistics and characteristics of various wetlands in the eastern forest region of Daxing'anling were analyzed. The results show that the eastern forest area of Daxing'anling is mainly divided into three wetland areas:Heilongjiang mainstream, Huma River and Nenjiang River source.The total wetland area is 153.08×10~4 hm~2, accounting for 18.33% of the total area. The main wetland types are swampy wetlands with an area of 147.11 ×10~4 hm~2, followed by river wetlands with an area of5.86 ×10~4 hm~2, and permanent freshwater lake wetlands and constructed wetlands with an area of 0.05×10~4 hm~2 and 0.06×10~4 hm~2.The wetland area of 10 forestry bureaus is 125.79 ×10~4 hm~2, 6 local forest farms are 7.1 ×10~4 hm~2 and 8 protected areas are 20.17 ×10~4 hm~2.
