Quantifying and Zoning Ecological Compensation for Cultivated Land in Intensive Agricultural Areas: A Case Study in Henan Province, China

Abstract

Cultivated land ecological compensation (CLEC) is an important way to solve regional development imbalance and cultivated land problems, and the scientific quantification of the ecological value of cultivated land is the key to CLEC. This study quantified the total amount and urgency of CLEC in China’s main grain-producing region using the cropland ecological footprint (EF) and ecosystem service value (ESV) methods. Furthermore, this study analyzed the comprehensive zoning of CLEC considering natural and economic development. The results showed that the spatial distribution of EFs and the ecological carrying capacity of cultivated land in Henan Province are similar, presenting the spatial characteristics of being high in the southeast and low in the northwest; the cultivated land in most of the counties and districts is in a state of ecological surplus, and the cultivated land resources are sufficient to support their own consumption needs. Henan Province as a whole is an ecologically compensated region, with a compensation amount of CNY 1.39 billion, and the total amount of compensation is in a positive value of 94.94%. The Southwest Yu and North Yu economic zone of Henan are the areas of high and low values of cultivated land compensation. The priority compensation region is the most extensive and widely distributed type in the five regions of Henan Province, accounting for 55% of the counties and districts. The degree of compensation is most urgent in the Huanghuai, Southwest Yu, and North Yu economic zones. This study’s findings provide new ideas for the development of differentiated ecological compensation policies, and provide references for the participation of multiple market participants and the diversification of compensation forms.
