土地利用变化引起的水文分量时空变化对认识流域产汇流过程,优化流域土地利用结构和水资源规划具有重要意义。基于SWAT模型,本研究以赣江流域为例,结合1980、2000、2015年3期土地利用数据从水文响应单元的角度,系统分析了单纯土地利用变化对流域产流、蒸发、入渗以及径流等主要水文过程时空分布的影响。结果表明:1980~2015年间,流域内的土地利用变化主要表现为耕地和林地的减少,城乡建设用地的增加;林地的减少和城乡建设用地的增加是产流增加,蒸发和入渗减少的主要原因;总体上,土地利用变化对局部地区水文过程影响较大,但因土地利用类型之间的相互转化和其影响的叠加,流域尺度上的综合水文效应明显降低;土地利用变化导致整个赣江流域平均径流量增加了2.33×108m3,相比较近年来赣江径流的减小幅度其影响十分有限。近年来,赣江入湖径流量的下降主要是由气候变化和其他人类活动作用特别是流域工农业用水的大幅增长所致。流域水文过程模拟应充分考虑土地利用变化水文效应的时空分异,注重天然和社会水循环的耦合,才能更为真实的反映流域水文过程,更好的为流域土地利用结构优化和水资源的高效管理提供科学依据。 相似文献

Land degradation is a global problem that seriously threatens human society. However, in China and elsewhere, ecological restoration still largely relies on a traditional approach that focuses only on ecological factors and ignores socioeconomic factors. To improve the effectiveness of ecological restoration and maximize its economic and ecological benefits, a more efficient approach is needed that provides support for policy development and land management and thereby promotes environmental conservation. We devised a framework for assessing the value of ecosystem services that remain after subtracting costs, such as the opportunity costs, costs of forest protection, and costs for the people who are affected by the program; that is, the net value of ecosystem services (NVES). To understand the difference between the value of a resource and the net value of the ecosystem service it provides, we used data on VES, timber sales, and afforestation costs from China's massive national afforestation programs to calculate the net value of forest ecosystem services in China. Accounting for the abovementioned costs revealed an NVES of ¥6.1 × 1012 for forests in 2014, which was 35.9% less than the value calculated without accounting for costs. As a result, the NVES associated with afforestation was 55.9% less than the NVES of natural forests. In some regions, NVES was negative because of the huge costs of human-made plantations, high evapotranspiration rates (thus, high water opportunity costs), and low forest survival rates. To maximize the ecological benefits of conservation, it is necessary to account for as many costs as possible so that management decisions can be based on NVES, thereby helping managers choose projects that maximize both economic and ecological benefits. 相似文献
