Cultivated land ecological security and spatial aggregation Pattern pattern in Hebei Provinceprovince

Scientific evaluation of ecological security situation and the pattern of cultivated land is the key to sustainable use of regional land and premises. The results showed that: County of Hebei Province, 138 were arable land ecological security spatial distribution pattern of aggregation, Moran’s I valueies was 0.630; range of memory in two provincial gathering area, gathering area by the high value of Shijiazhuang, Handan, Xingtai, and formed a total of 23 counties, the average arable land ecological security index was 0.377, low accumulation area from the Zhangjiakou and Chengde most of the composition, a total of 22 counties, the average arable land ecological security index 0.169; high value of the Theil index for large counties and the region gathered in the low accumulation area; macro perspective on the topography, rainfall, soil, land quality and other factors were the spatial distribution and aggregation patterns of the main drivers of differences. Land ecological security evaluation of Pattern Analysis and space science gathered designated areas of regional ecological security features to protect the region provide the scientific basis of food safety.
