摘要： 土地利用的多功能性决定了土地利用效益的多样化。通过构建土地利用效益评价指标体系、效益测度指数与耦合协调发展度模型,探讨了环渤海地区县域土地利用的社会效益、经济效益、生态效益、耦合格局及其协调发展特征。研究表明:环渤海地区土地利用效益的空间分异性与集聚性特征显著;经济社会中高值区主要分布在沿海地区和内陆平原区,生态高值区以冀西北间山盆地、坝上高原和辽宁山地丘陵区为主;从土地利用效益耦合度类型看,环渤海地区磨合阶段区域数量最多,占研究区的63.9%,集中分布于冀中冀南和山东省;低度耦合、拮抗阶段的区域呈带状环绕环渤海北部地区;高度耦合区域呈现出散乱的点状空间分布格局;协调发展度指数显示,轻度失调区占据主导地位,其次是初级协调区域,滞后失调区域数量较少,分别占环渤海地区总面积的51.09%、31.76%和10.87%。通过划分土地利用类型区,制定差别化区域土地利用政策,加强区域土地管理与规划,建立健全区域利益协调与补偿机制,是今后统筹协调土地利用的社会经济生态效益的重要方向。

Abstract: Multi-function of land use determined its diverse efficiency. While, there are fewer studies which evaluated land use efficiency based on comprehensive measurement at the regional scale. It is time to carry out similar studies. The arm of this paper is to compare the main benefit of land use at different counties around Bohai Rim. At first; we constructed evaluation index system of land use efficiency, benefit measurement index, and coupling degree models. And then, we analyzed social, economic and ecological benefits of land use and its temporal- spatial coordination characteristics at the county level around Bohai Rim, which is chosen as a case study area. The conclusions can be drawn as follows. (1) It is quite obvious that land use benefits presented characteristics of spatial distinction and agglomeration. High economic value zone distributed in coastal area and inland plain area, while high ecological value zone in the basin of northwest Hebei mountains, Hebei Bashang Plateau, and mountain areas of Liaoning. (2) Based on the analysis of coupling degree models, the stage of running areas had the most numbers, which is accounting for 63.9% of the total units. (3) Coupling degree indexes showed that minor imbalance areas occupied leading position, the second is the primary coordinating regional, which are accounting for 51.09% and 31.76% of the total areas, respectively. So, it needs to put forward to control these regional problems. These measures, including dividing land use zone which can make the leading function of county land use clearly, making different land use policy, enhancing land management and planning, establishing and perfecting interest coordination and compensation mechanisms, are comprehensive ways to solve the coordination of land use benefits.
