江西省林地变化的时空特征与驱动因数分析

Temporal and Spatial Characteristics and Driving Factors of Forest Land Change in Jiangxi

林业资源问题受到越来越多人的关注,保护林业资源已经成为刻不容缓的任务。以江西省为研究区域,根据1978—2015年江西省林地资源的统计数据,分析江西省林业面积、森林覆盖率随时间变化的特征。以2015年江西省各市的林业面积和森林覆盖率的数据为基础,分别制作出江西省各市林业面积的分类图和森林覆盖率图。同时选取影响江西省林地变化的10个社会经济因素,采用Pearson系数法进行社会经济驱动因素相关性分析,结果表明,农村人口数量与林业面积变化呈负相关;年末总人口、城市化率、财政收入等社会经济因素都与林地面积呈正相关。充分利用好社会经济驱动因素,为未来增加林地面积、提高森林覆盖率提供有效的参考依据。

The problem of forest land resources has attracted more and more people’s attention,it is very urgent for people to protect forest land resources.Taking Jiangxi Province as a research area,according to the statistical data of forest resources in Jiangxi Province from 1978 to 2015, we analyzed the characteristics of forest area and forest coverage over time. Based on the data of forest area and forest coverage of each city in Jiangxi Province in 2015, the classification map of forest area and forest coverage rate map had been drawn.At the same time,we selected 10 socioeconomic factors affecting the change of forest land in Jiangxi Province and analyzed by Pearson coefficient method. The results showed that the number of rural population was negatively related to the change of forest area, the total population, urbanization rate, financial income and other socioeconomic factors were positively related to forest land area at the end of the year.Making full use of the socioeconomic driving factors provides an effective reference to increase forest area and forest coverage in the future.
