This paper proposes an index system to calculate the agricultural land use intensity of 30 provinces,autonomous regions,and municipalities in mainland China,and calculates the agro-climatic suitability by spatial interpolation.Based on this,by comparing the spatial relationship between them the obtained conclusions are as follows:(1) In general,the agricultural land use intensity in Eastern China is higher than Western China.Spatial distribution of the agro-climatic suitability is digressive from southeast to northwest of China.In a certain extent,the agro-climatic suitability restricts the distribution of agricultural land use intensity,but the spatial dependency can be changed by the improvement of agricultural land use intensity.(2) Overall the agricultural land use intensity in China has a rising trend from 1995 to 2005.The trend in lower agro-climatic suitability regions is more remarkable.(3) Based on the relationship between agricultural land use intensity and suitability of agro-climate,suggestions were made to make intensive management of agricultural land by adjusting measures to local conditions.
