Abstract:Cultivated land is the material basis for human survival,and the protection of cultivated land is of great significance for maintaining food security. In view of the main practical risks faced by cultivated land,the theoretical framework,index system and evaluation model of cultivated land sensitivity evaluation were constructed from the perspective of “ agricultural production-urban development-ecological maintenance". Taking Hebi city as an example,the comprehensive evaluation of cultivated land sensitivity was carried out by using GIS spatial analysis method,and the degree of cultivated land sensitivity in Hebi city and the spatial distribution characteristics of the region were quantitatively revealed. The results were as follows ：（1） The comprehensive sensitivity of cultivated land in Hebi city was mainly mild sensitive area and moderate sensitive area,accounting for 39. 78% and 34. 35% respectively. （2） The highly sensitive and extremely sensitive areas were mainly distributed in the western mountainous areas and the surrounding area of Hebi city,and the moderately sensitive areas were mainly distributed in the intersection of mountainous and plain areas in the middle of Hebi city and the northern part of Xun county,and lightly sensitive and insensitive areas were mainly distributed in southern part of Xun county. （3） The cultivated land in Hebi city could be divided into ecological conservation area,urban restricted area,main grain production area and comprehensive improvement area,and different utilization directions and protection measures were proposed according to the dominant sensitive factors in different areas.

Key words:cultivated land evaluation;cultivated land protection;sensitivity;GIS;Hebi city
