- 摘要:
- 提高土地生态效益是煤炭城市土地有效利用的重要途径之一，以煤炭城市黑龙江省鹤岗市为例，根据土地利用生态现状、资源开发状况以及城市所处的经济发展阶段，从土地生态承载力、土地生态状态和土地生态响应等方面，选择有代表性的24个指标，构建了鹤岗市土地生态效益评价指标体系，采取综合评价法和协调度分析法，对鹤岗市2001-2007年土地生态效益进行定量评价及分析。研究结果表明，2001-2007年，鹤岗市的土地生态系统协调度和土地生态综合效益具有正相关性且呈有序上升的趋势。2001-2003年土地生态系统处在不协调状态。2004-2006年土地生态状况处于基本协调的状态，2007年，土地生态系统比较协调。2001-2007年，鹤岗市的土地生态效益综合评价值在0.10～0.21之间小幅度上升，处于低下水平，表明鹤岗市的土地生态效益水平还有很大的提高空间，并可以通过提高土地生态效益协调度的方式来提高区域土地生态综合效益。
- Abstract:
- Improving land eco-efficiency is one of the important ways of land effective-use in Coal City. Taking the coal city(Hegang city in Heilongjiang)for example, according to the ecological status of land use, resource development status,and its economic development stage, this paper builds eco-efficiency evaluation index system of land in Hegang city choosing 24 representative indicators from the aspects of ecological carrying capacity of land,ecological status of land and ecological response of land, etc. and quantitatively evaluates and analyzes the eco-efficiency of land in Hegang city from 2001 to 2007 adopting comprehensive evaluation method and coordination degree analysis method. The results showed that from 2001 to 2007, the coordination degree of land ecosystem and land ecological comprehensive benefits had an orderly increase in positive correlation in Hegang city. From 2001 to 2003, the land ecosystem was in the uncoordinated state in Hegang city. From 2004 to 2006, the ecological status of land was in the basic coordination state in Hegang city. In 2007, land ecosystem was harmonious in Hegang city.From 2001 to 2007, in Hegang city, the comprehensive evaluation values of eco-benefits of land were ranging from 0.10 to 0.21 with a minor rise but still at an extremely low level. Thus, there is still much room for improvement on the eco-benefits level of land in Hegang, and the comprehensive eco-benefits of regional land can be improved by raising the coordination degree of land eco-benefits.
