摘　　要：文中选择典型地段对尚志市帽儿山地区的沼泽与水湿地分布规律、形成原因进行了探讨,并根据土壤及水分条件对沼泽与水湿地进行了分类,并对改良土壤后水湿地上的落叶松、云杉人工林的生长状况进行了研究。结果表明,该地区的沼泽与水湿地多分布于地势平坦的河流附近的采伐迹地和火烧迹地上,它的形成是气候、地貌、水文条件综合作用的结果;按土壤及水分条件的差异大体可将其分成三类,对于不同类型水湿地需采用不同的改造和利用方式。这些研究结果为帽儿山地区的沼泽与水湿地改良及利用提供了科学依据。Through studying on distribution characteristic and forming reason,classifying on the basis of soil and moisture condition and investigating the growth state of Laxis olgensis and Picea koraiensis planted on artificial improved area of marsh and wetland on Maoershan in Shangzhi City,the results are obtained as follows: most of the marsh and wetland are distributed on firing and felling blank on smooth terrain near river,its formation is integrated affection of climate, landform and hydrographical condition and can be devided into three kinds according to soil and moisture condition;marsh and wetland can be transformed according to different characteristic of different kinds.These results provide scientific foundation for marsh and wetland improvement.
