Abstract:The analysis of the spatial pattern of resource environmental carrying capacity （ RECC） at city and county level can guide the optimization of regional land space layout. Based on the analysis of land spatial function and the characteristics of resource flow ， the evaluation index system of resource environmental carrying capacity at city and county level was constructed ， and the spatial pattern differentiation characteristics of re-sources and environment carrying capacity in Hebi city from three perspectives were studied by ClS spatial analysis method. The results showed that the spatial differentiation characteristics of resource environmental carrying capacity in Hebi city were obvious. The areas with high level of RECC from the perspective of ecology were mainly distributed in the western part of Hebi. The areas with high level of RECC from the perspective of agriculture were mainly distributed in central and eastern part of Hebi.'The areas with high level of RECC from the perspective of the city construction were mainly distributed in central and northeast part of Hebi.The regional proportion with high level of RECC from the perspective of agriculture was the largest ， accounted for 56.02% ， with an area of 1 199.11 km2 .There was a significant spatial positive correlation among the three perspectives of resource environmental carrying capacity in Hebi ， and the spatial clustering characteristics and hot spots distribution of the three perspectives were significantly different.

Key words:Hebi city;resource and environment;carrying capacity;spatial pattern;differentiation
