| Abstract: |
| Based on statistical data of agricultural eco-economy in Shaanxi Province, a comprehensive evaluation index system for agricultural eco-economy was built; Using entropy weight method to determine the weight coefficients, comprehensive assessment was made of agricultural eco-economy system in various counties (districts) of Shaanxi; Then based on self-related theories of spatial distribution of geographic things, their distribution in space and the aggregation characteristics were further explored. The results showed that the province's agricultural eco-economy has fluctuated greatly in the past ten years. There was a decreasing trend of spatial differences from Xi'an, as the center of the Guanzhong region, to the northern and southern parts of Shaanxi in 2007. The relations between agricultural eco-economy system and its subsystems in every county (districts) have a larger difference. Coordination of the inter systems in counties (districts) of Guanzhong area is the best while that in northern Shaanxi was the worst. Agricultural eco-economy level of counties (districts) in the province in 2007 mainly tended to low-low aggregation. During the this period of time, the agricultural eco-economy level in the counties (districts) in Xi'an and its surrounding area showed high-high aggregation, while that in the northern and southern parts of Shaanxi turned out low-low aggregation. In addition, the agricultural eco-economy level in a few cities and counties at the edge of Guanzhong region showed non-aggregation, and these cities and counties were mainly located in concentration at the edge of high high aggregation area. |
