| 摘 要： | 利用相关性分析、逐步回归、灰色关联等方法,分析气象、社会经济因子对江苏省区域植被覆盖的影响。结果表明:气象因子是江苏省植被覆盖的主要影响因素,人类活动协同气象因子产生影响。植被覆盖度与春、夏、秋、冬四季气温和年日照时数呈显著或极显著的相关关系.与年降水量呈单峰曲线关系。其中四季气温是植被覆盖的主要驱动因子。若在气候环境不发生异常变化的条件下,发展集约型经济.合理利用土地资源并有效控制人口增长等社会经济因子将有利于提高江苏省区域植被覆盖度,实现生态经济可持续发展。

| Abstract: | Taking Jiangsu province as an example,the author studied the climate and socio-economic factors impact on the regional vegetation cover with correlative analysis,stepwise regression and grey relation analysis.The results showed that vegetation cover in Jiangsu province was strongly influenced by climate factors interacting with human activities.The vegetation cover significantly correlated with four seasonal temperature values and sunshine hours,of which temperature was the mainly effected climate factors.... |
