为研究土地整理对耕地生态价值的影响,采用替代法及市场定价法等方法,探讨了皖南村域尺度上沪皖现代烟草农业高科技示范园土地整理区的耕地生态价值及其变化.研究结果表明,项目区耕地气体调节价值、营养循环价值和水源涵养价值3种生态价值在整理前分别为58.46、15.11和0.35万元,气体调节价值最高,水源涵养价值最低.土地整理完成后,3种生态价值均有增加,其中营养循环价值增加6.23万元,增加量最高;水源涵养价值增值率最高,达到整理前的12.5倍.整理后耕地的总生态价值增加了13.94万元,增值率为18.86%.因此,该村域尺度的土地整治项目实施后其生态效益显著,研究结果将对烟田耕地有效利用及后续土地整理实践提供重要的借鉴与指导.

To study the effect of land consolidation on farmland ecological value, the Hu-Wan science-technology demonstration garden of modern tobacco agriculture, which located at a small village of South An Hui province, was selected as an example to study the ecological benefit before and after the land consolidation using the method of substitution and market pricing. The results showed that the values of gas regulation, nutrient cycling and water conservation before the land consolidation were 584,600 yuan, 152,000 yuan and 3,500 yuan respectively, the highest value was gas regulation value, and the minimum was water conservation value. After the land consolidation, the three ecological values were all increased, and the nutrient cycling value increased by 62,300 yuan, which was the highest increase; the value-added rate of water conservation value was the highest with nearly 12.5 times. The arable land ecological value increased by 139,400 yuan and the value-added rate was 18.86%. So, the ecological benefit of land consolidation of the science-technology demonstration garden of modern tobacco agriculture on village scale was prominent. And this result will be an important guidance to the effective utilization of tobacco land and the subsequent land consolidation practice in the future.
