生态系统服务价值评估是当前生态经济学和环境经济学的研究热点和焦点。耕地生态适宜性评价 是对影响耕地各种条件的综合评估,其结果能从一定程度上反映耕地的质量状况。该文首先选取了影响章 丘市耕地生态适宜性的因子,在对研究区域进行生态适宜性评价的基础上,以生态适宜性综合指数为修正 因子对耕地生态系统服务价值进行修正,使得耕地生态系统服务价值因为其生态适宜性的不同产生了区 别。研究发现,章丘市的耕地生态系统服务价值从南往北逐步减少,耕地适宜性综合指数能较好的修正耕 地的生态系统服务价值。 |

Abstract: |
The evaluation of ecosystem service value is the hotspot in the ecological economics and environmental economics. Cultivated land ecological suitability evaluation is an activity to estimate all the impact factors, from which the result can reflect the situation of the cultivated land. This paper selected the factors that influence the ec- ological suitability evaluation, and on the basis of the evaluation of the ecological suitability modified the ecosystem service value of cultivated land by using the ecological suitability index, which distinguished the ecosystem service value due to the cultivated land ecological suitability. The result showed that the ecosystem service value of cultivat- ed land decreased gradually from south to north, and the index of ecological suitability can well modify the ecosys- tem service value. |
