县域土地利用协调发展度评价——以河北省曲周县为例

土地利用协调发展度评价对指导区域土地资源利用具有重要意义。以河北省曲周县为例,从土地利用的社会经济发展水平和生态环境质量两个方面建立土地利用协调发展度评价指标体系,并构建评价模型,对曲周县域的土地利用协调发展度进行综合评价。研究结果表明,曲周县土地利用属于中级协调发展类经济滞后型,土地利用的社会经济水平与生态环境质量状况间处于高度协调状态,但土地利用的综合效益水平低下,与生态环境效益相比,其社会经济效益略显滞后。在此基础上,运用经济学中的库兹尼茨曲线进行区域土地利用模式的选择,表明曲周县土地利用应选择跨越式发展模式,即沿着库兹尼茨曲线中的NSFYPW轨迹曲线发展。

Evaluation of Coordinated Development Degree of Land Use at County Scale-A Case Study at Quzhou County of Hebei Province

It is very significant of land use coordinated development degree evaluation to instruct land resource use. As an example, Quzhou county of Hebei province, the indices system and the model of evaluation of coordinated development degree of land use was established according to the level of society-economy development and the quality of environment. Then the degree of coordinated development degree of land use in Quzhou County was evaluated integrativly. The result of this research indicated that it is of the type of intermediate coordinated development and economy-lagged, and the level of society-economy development is in perfect harmony with the quality of environment of land use in Quzhou County. But the level of land use integrative benefit is low, society-economy benefit is lagged appreciably, compared with environment benefit.Then according to the Kuznet's curve in economics, the land use mode choice is analyzed. The result indicated that the NSFYPW track mode of land use in Quzhou County should be chosen.
