摘要
本文以回归统计和相关分析为手段,对修水县和江西省的森林资源和人口统计资料进行分析,初步揭示了人口密度与森林覆被率之间的数量变化规则,并据以建立起相应的双曲线回归模型,进而作出发展预测。
By means of regression statistics and relative analysis ,the article analyses the forest resources and the population statistical data both of Xiushui Country and of Jiangxi province. It preliminarily shows the date-ray regulation between population density and forest-covering rate,and constructs a relative hyperbola regression model on its basis, and finally makes a developing forecast.
