采砂采石新增占用林地与区域社会发展间的关系研究

Relationship between Regional Social Development and Newly Occupied Forest Land by Sand and Stone Mining

为预测采砂采石场建设对林地的需求,科学制定林地保护利用规划,采用昭通市森林督察数据库中提取的各县区数据和相关社会经济情况组成33个样本,利用线性回归分析方法研究影响采砂采石与相关社会发展因素之间的关系。结果表明,区域人口、GDP、农村居民收入、林地占国土面积的比例在0.1水平上与砂石场新增图斑数呈线性关系,其中农村居民收入与砂石场新增图斑数呈负相关关系;而城镇居民收入与砂石场新增数量间无相关关系。

In order to predict the demand for forest land for the construction of sand quarries and scientifically formulate forest land protection and utilization plan,the data of each county and district extracted from Zhaotong forest inspection database and relevant social and economic conditions were used to form 33 samples,and the relationship between sand and stone mining and relevant social development factors was studied by using linear regression analysis.The results showed that the regional population,GDP,rural residents′income,and the proportion of forest land to the land area were linearly related to the number of new spots in sand and stone mining at the level of 0.1,and the rural residents′income was negatively related to the number of new spots,while the urban residents′income had no correlation with the number of new spots.
