| 摘要: |
| 为全面认识耕地资源价值结构组成，探索其空间分布规律，完善耕地保护补偿机制，以山西省长治市襄垣县为研究对象，应用收益还原法、成本替代法、生物当量因子法等方法对山西省长治市襄垣县耕地资源价值进行核算，对其空间分布规律进行探究。结果表明:1)襄垣县2017年耕地资源价值为75.57万元/hm2，其中耕地资源经济价值为26.23万元/hm2，生态价值为25.4万元/hm2，社会价值为23.94万元/hm2；2)高程、坡度这两类地形因子对襄垣县耕地资源价值存在显著负面影响，大面积的矿山开采对襄垣县耕地资源价值有一定的负面效应；3)距河流、国道、高速公路、县道的距离与耕地资源价值不存在显著的相关性，距主要道路与乡道的距离与耕地资源价值呈显著负相关，距省道和铁路的距离与耕地资源价值呈显著正相关。本研究可为核算耕地资源价值，分析其空间分布规律和耕地保护提供参考。 |

| Abstract: |
| In order to fully understand the value structure of cultivated land resources, explore its spatial distribution rules, and improve the compensation mechanism for cultivated land protection, Xiangyuan County, Changzhi City, Shanxi Province was taken as an example, Income reduction method, cost substitution method, biological equivalent factor method and other methods were adopted to evaluate the cultivated land resources in Xiangyuan County, its spatial distribution law was explored. The results showed that: 1)The value of cultivated land resources in Xiangyuan County in 2017 was 755 700 yuan/hm2, the economic value of cultivated land resources was 262 300 yuan/hm2, the ecological value was 254 000 yuan/hm2, and the social value was 239 400 yuan/hm2; 2)The two types of terrain factors, elevation and slope, had a significant negative impact on the value of cultivated land per unit area in Xiangyuan County, Large-scale mining had a certain negative effect on the value of cultivated land resources in Xiangyuan Coungty; 3)There was no significant correlation between the distances from river, national highway, expressway, and county road and the value of cultivated land resources, the distances from main road and village road were significantly negatively correlated with the value of cultivated land resources, the distances from provincial highway and railway were related to the value of cultivated land resources and there was a significant positive correlation. In conclusion, this research can provide references for the evaluation, spatial pattern analysis and protection of cultivated land resource. |
