【摘要】：在推进新型城镇化和生态建设的背景下,客观定量评价区域生态环境状态,是当前我国生态建设重要而紧迫的任务之一。高密度的人类活动会对自然生态系统产生超负荷的压力,通过生态承载力的分析能够定量测度这种状况,为区域可持续发展提供借鉴意义。基于生态足迹模型,计算了2008年和2013年武汉城市圈各县域单元的生态足迹/承载力,并进行了时空变化分析。研究发现武汉城市圈各县域单元的生态足迹和生态承载力在空间上存在显著的差异性,生态足迹逐年增加,生态承载力的变化相对较小,出现两级分化的现象。根据生态足迹/承载力进行跨区县生态补偿测算,得到2008年和2013年武汉城市圈48个县域的转移支付情况,表明如果运用财政转移支付的手段,整个区域能够达到生态系统供给和需求动态平衡的目标,缓解武汉城市圈的生态压力,实现武汉城市圈的可持续发展。
[Abstract]:In the context of promoting new urbanization and ecological construction, the objective and quantitative evaluation of regional ecological environment state. Ren Wuzhi is an important and urgent ecological construction in China at present. High density of human activities will cause overload pressure on the natural ecosystem, which can be quantitatively measured through the analysis of ecological carrying capacity. Based on the ecological footprint model, the ecological footprint / carrying capacity of each county unit in Wuhan City Circle was calculated in 2008 and 2013. It is found that the ecological footprint and ecological carrying capacity of the county units in Wuhan City Circle are significantly different in space, and the ecological footprint is increasing year by year. The change of ecological carrying capacity is relatively small, there is a phenomenon of two-level differentiation. According to the ecological footprint / carrying capacity of cross-county ecological compensation calculation. In 2008 and 2013, the transfer payment situation of 48 counties in Wuhan City Circle is obtained, which shows that if the means of fiscal transfer payment are used. The whole region can achieve the goal of dynamic balance of ecosystem supply and demand, alleviate the ecological pressure of Wuhan city circle, and realize the sustainable development of Wuhan city circle.
