摘要
该文在深入分析土地整理生态效益评价问题特点的基础上,将基于生态足迹模型的生态承载力定量计算应用到陕西省土地整理工程中,并按土地整理地貌分区对生态承载力进行分析计算。研究结果表明,实施土地整理后陕北黄土高原沟壑区、渭北黄土台塬区、关中平原区人均生态承载力分别净增加0.0538hm2、0.0735hm2和0.0698hm2;人均生态赤字分别减少了21.33%、18.27%和36.95%。可见通过土地整理有效缓解了陕西省的生态环境压力。
The paper analysis problem of ecological environmental evaluation of land consolidation, calculation on ecological capacity which is used the land consolidation project based on ecological footprint model, and quantify evaluation the ecological capacity of geomorphologic land consolidation division of regions. Results show that increase by 0.0538 hm^2, 0.0735 hm^2 and 0.0698 hm^2 of ecological carrying capacity; ecological deficit per capita decrease by 21.33%, 18.27% and 36.95% in the loess hilly and gully region of Northern Shaanxi, Weibei losses plateau region, and Guanzhong plain. Land consolidation can effectively alleviate the pressuring on the ecological environment.
