摘要 研究目的:剖析近20年山东省生态用地时空演变特点,划分不同保护区域,为编制国土资源空间规划、保护生态用地提供参考。研究方法:采用环境库兹涅兹曲线(EKC),判断全省生态用地的发展趋势;根据洛伦兹曲线(Lorenz Curve)和基尼系数(Gini)方法,描述全省生态用地的分布及其演变特征;利用地理信息系统(GIS),遥感(RS)等方法获取数据并输出计算结果。研究结果:1996年以来全省生态用地总面积减少了46.8×10^4hm^2,减少态势具有明显的"平稳-加速-减缓"的阶段性特征;全省生态用地分布基尼系数由1996年的0.523降低为2016年的0.480,生态用地区域分布趋于均衡。研究结论:(1)随着生态文明建设和美丽中国战略的深入实施,将来有可能出现生态用地由减少到增加的拐点;(2)本文把全省划分为三类不同的保护区域,并根据不同保护区的特点提出了差别化的土地利用方向和生态保护政策。 The purpose of this study is to analyze the temporal and spatial evolution characteristics of ecological land in Shandong Province during the last 20 years,and to identify different protection areas,so as to provide reference for the spatial planning and ecological land conservation.Environmental Kuznets Curve (EKC)was used to simulate the development trend of ecological land in the area;Lorenz Curve/Gini were used to describe the distribution and evolution characteristics of the ecological land;GIS and RS were used to obtain data and output results.The results show that the total area of ecological land in Shangdong Province has decreased by 46.8× 10^4 hm^2 since 1996,and the reduction rate has a remarkable "stable-acceleration-slow down"stage characteristics.The Gini coefficient of ecological land distribution in Shangdon is gradually reduced from 0.523 in 1996 to 0.480 in 2016,and the regional distribution characteristics of ecological land tend to be balanced.It concludes that:1)under the construction of ecological civilization and the implementation of the beautiful China strategy,a turning point from decrease to increase of the ecological land evolution trend would probably occur in the near future.2)This paper identified three kinds of ecological protection areas and put forward different land use direction and ecological protection policies.
