| 摘 要： | 利用实地调查和实验数据分析,构建了玄武湖菹草种群存在下的生态因子场,直观地展示出各项理化因子在空间的分布状况,体现了水环境的空间异质性.通过对生态因子场的特征分析,确定玄武湖菹草种群的密度与透明度、水深/透明度、浊度、pH值、硝酸盐NO3--N含量具有空间相关性,而与总氮和总磷含量无明显的空间关联性.

| Abstract: | Water sampling was carried out in the Xuanwu Lake at 31 stations with assistant of GPS setting.The results of field survey and laboratory analysis were put into computer to establish the GIS database of the lake.Under the support of software Arc Gis 9.0,ecological factor fields were simulated using Kriging interpolation technique.Ecological factor field was presented to quantify spatial heterogeneity in bound inland waters.Based on analysis of Xuanwu Lake ecological factor fields characteristics,it was dedu... |
