东洞庭湖湖滨带不同生态功能区土壤有机质空间分异特征

摘要

This ariticle studies the spatial variation characteristics of soil organic matter by statistical methods for seven different ecological function zones in East Dongting lakeside belts .According to the results ,the horizontal variation feature of soil organic matter contents among the seven zones are Jun Moutain Tourism Area ﹥ Lu Lake Reed Field ﹥ Caitang Wetland Area ﹥ Yueyang Downtown ﹥ Matang Residential Area ﹥ Tuanzhou Farm ﹥Chenglingji Port from high to low .As for the vertical variation characteristics ,the soil organic matter contents are reducing gradually from top to bottom except in Chenglingji Port and Yueyang Downtown .The findings can provide basic reference for pollution control in the East Dongting Lake .%运用统计学方法研究了土壤有机质在东洞庭湖湖滨带不同生态功能区的空间分异特征。结果表明：土壤有机质的水平分异为君山旅游区﹥漉湖芦苇区﹥采桑湖湿地区﹥岳阳市区﹥麻塘居民区﹥团州农场区﹥城陵矶港口区；土壤有机质的垂直分异为除城陵矶港口和岳阳市区外，其余功能区的有机质含量都是从上到下递减，希望为治理东洞庭湖环境污染提供理论指导。
