【摘要】 土壤是湿地生态环境的重要组成部分,其空间分布格局对湿地生态系统结构有重要影响.通过对遥感影像解译和历史资料分析,结果表明鄱阳湖典型湿地土壤的空间分布格局与鄱阳湖季节性水位涨落产生的湿地覆盖空间分布具有相似关系,同时也与河流三角洲的空间形态存在密不可分的联系.在所有的影响因子中,鄱阳湖水陆相互作用过程和人类活动既是典型湿地覆盖动态变化的两个主要影响因子,也是目前湿地土壤及其空间分布格局形成的决定性影响因子.更多还原

【Abstract】 The soil is an important component of wetland ecological environment,and the distribution pattern of soil impact greatly on the wetland ecosystem structure.Based on the analyses of remote sensing interpreting results of landsite images and historical data of soil and land cover and water level observation,the result can be concluded that wetland soil’s distribution pattern is comparability to the delta’s spatial configuration and land cover distribution pattern influenced mainly by the seasonal fluctuation of water level of poyang lake,and both of the reciprocity between lake and land and human activities had been playing very important roles on the dynamic change of wetland cover and on the present soil’s distribution pattern in the typical wetland area,the former is the main power of the formation of soil’s distribution belts circling poyang lake,and the other had reduced to space and time change of soil type.更多还原
