东北地区沼泽湿地空间分布格局及其影响因素分析

Spatial Distribution Pattern of Marsh Wetland in Northeast China and Its Influencing Factors

在分析东北地区沼泽湿地空间分布格局的基础上,利用逐步回归模型筛选出影响湿地空间分布的生态因子。研究结果表明,沼泽湿地的空间分布格局受气候、水文、地貌和人类活动等条件的制约,其中相对湿度和年平均降雨量有利于沼泽湿地的形成,而人口密度、坡度和气温不利于沼泽湿地的形成。

Ecological factors which affect the spatial distribution of wetlands were selected by stepwise regression analysis based on the spatial distribution pattern of marsh wetlands in Northeast China.Results show that the spatial distribution pattern of the marsh wetland is affected by climate,hydrology,physiognomy and human activities,among which relative humidity and annual average rainfall are conducive to the formation of wetlands,but population density,slope gradient,and air temperature are not conducive.
