土地利用程度与效益耦合协调方法研究——以阿鲁科尔沁旗为例

以阿鲁科尔沁旗为研究区域,以所属各乡镇为研究单元,运用土地利用程度综合指数、综合效益指数及耦合度与协调度模型,对全旗各乡镇土地利用程度与效益的空间差异及耦合度与协调度进行分析。结果表明:全旗土地利用程度呈中等状态,14个乡镇土地利用程度综合指数平均值为203.2;土地利用综合效益指数平均值为1.160,土地利用经济效益、生态效益、社会效益指数平均值分别为0.451、0.392、0.317;土地利用程度和土地利用效益空间差异较大,土地利用效益从区域中心向外围呈逐渐增加趋势;土地利用程度和效益的耦合度平均值为0.454,总体呈拮抗状态,协调度平均值为0.308,总体呈中度协调状态,土地利用程度与效益间的协调度与耦合度居高的乡镇多为牧草地占多数和以畜牧业为支撑产业的乡镇。

Study on coupling and coordination method of land use degree and benefits: a case study of Ar Khorqin Banner

Taking the Ar Khorqin Banner as the research area and using the respective towns as the research units, the spatial difference of land use degree and benefit as well as the coupling degree and coordination degree were analyzed by using the land use degree comprehensive index, the comprehensive benefit index, and the model of coupling degree and coordination degree. The results showed that the land use degree of the whole banner was in a moderate state, and the average value of the comprehensive index of land use degree of the 14 towns was 203.2. The average value of land use comprehensive benefit index was 1.160, and the average value of land use economic benefit, ecological benefit and social benefit index was 0.451, 0.392 and 0.317, respectively. The spatial difference of land use benefit was great and the land use benefit increased gradually from the regional center to the periphery. The average value of the coupling degree between land use degree and benefit was 0.454, showing antagonism on the whole, and the average value of the coordination degree was 0.308, showing moderate coordination on the whole. The towns with high coordination degree and coupling degree between land use degree and benefit were mostly grassland and areas with animal husbandry as the supporting industry.
