摘要:

针对区域土地利用与生态环境系统的特点,建立了土地利用与生态环境协调评价的指标体系和复合物元模型,以哈尔滨市为例,对各县级单元进行了土地利用与生态环境协调的空间差异评价。结果表明:①物元分析理论对区域土地利用与生态环境评价具有明显的适用性,评价结果显示出哈尔滨市域内土地利用与生态环境协调状况的空间差异明显;②基于复合物元模型进行评价,通过单指标信息可以找出影响区域土地利用与生态环境协调发展的关键问题,如大多数县级区域存在土地集约利用水平较低、面临土壤污染、土壤侵蚀及湿地生态功能脆弱等土地生态环境风险,符合研究区的实际情况;③只有合理制定区域差异化的土地生态环境管制措施,积极引导对土地退化等问题的防治,才能实现区域土地可持续利用、生态环境质量改善和区域可持续发展。

Abstract:

Based on regional land-use and eco-environment system, an index system and complex matter element model were established. The evaluation model was applied to Harbin City, at the scope of which the assessment of spatial differences of the land-use and eco-environment situation among the county-level regions were conducted. The results indicated that: Firstly it is applicable for the matter element analysis to deal with the evaluation of regional land-use and eco-environment. The result revealed that there were obvious spatial differences among the county-level regions in terms of the land-use and eco-environment coordination situations. Secondly, the single index information based on the matter element model helps to find out the key elements affecting the land-use and eco-environment coordination situations, for example, most county-level regions are confronted with relatively low intensive land-use level and eco-environmental risks such as soil pollution, soil erosion and fragile ecological functions of wetland. The research result coincides with the actual situation. Thirdly, regional sustainable land-use, improvement of eco-environment quality and sustainable regional development of Harbin City depend on formulating different regional measures for land eco-environment control and active guidance to prevention and control of land degradation, and etc.
