【摘要】：基于江蘇省縣域單元2001—2011年的面板數(shù)據(jù),運(yùn)用Arc GIS空間分析技術(shù),分析2011年江蘇省縣域農(nóng)田利用經(jīng)濟(jì)效益的空間分布規(guī)律和地域差異,并利用泰爾指數(shù)和變異系數(shù)等區(qū)域差異統(tǒng)計(jì)方法分析10年間江蘇省縣域農(nóng)田經(jīng)濟(jì)密度的動態(tài)差異特征。結(jié)果表明,(1)江蘇省農(nóng)田經(jīng)濟(jì)密度整體呈現(xiàn)不斷上升趨勢,截至2011年形成蘇錫常高值連綿區(qū)和蘇北個別縣域高值區(qū);(2)2001—2011年縣域間農(nóng)田經(jīng)濟(jì)密度動態(tài)差異呈現(xiàn)大幅度波動態(tài)勢,但蘇南、蘇中、蘇北3個區(qū)域間的區(qū)間差異始終處于波動性增大趨勢,另外3個區(qū)域所轄縣區(qū)的內(nèi)部差異大小順序?yàn)樘K北蘇中蘇南;(3)2001—2011各縣區(qū)農(nóng)田經(jīng)濟(jì)密度相對發(fā)展速率變化幅度較大,整體順序?yàn)樘K南蘇北蘇中,10年間各縣區(qū)發(fā)展速度是2011年現(xiàn)狀形成的基礎(chǔ)。研究縣域農(nóng)田經(jīng)濟(jì)密度空間演變及區(qū)域差異有利于蘇南、蘇中、蘇北根據(jù)自身情況制定恰當(dāng)?shù)霓r(nóng)業(yè)發(fā)展策略,為協(xié)調(diào)區(qū)域農(nóng)業(yè)發(fā)展、制定農(nóng)業(yè)產(chǎn)業(yè)政策提供依據(jù)。
[Abstract]:Based on the panel data of the county unit of Jiangsu province from 2001 to 2011, the spatial distribution rules and regional differences of the economic benefits of the farmland utilization in Jiangsu province in 2011 are analyzed by Arc GIS spatial analysis technology, and the dynamic density of farmland economic density in the county of Jiangsu province is analyzed by using the regional difference statistical methods, such as the Tel index and the coefficient of variation, and so on. The results show that (1) the overall farmland economic density in Jiangsu province is rising constantly. As of 2011, there was a high value area of Subei high value continuous zone and a few counties in Northern Jiangsu Province. (2) the dynamic difference of farmland economic density between counties in 2001 - 2011 showed a large amplitude wave dynamic potential, but the interval difference between the 3 regions of the northern Jiangsu Province, the middle of the Soviet Union and the northern Jiangsu Province began. In the end, the trend of fluctuation is increasing, the order of the internal difference between the counties under the jurisdiction of the other 3 regions is South of Jiangsu in Subei Jiangsu Province. (3) the relative development rate of farmland economic density varies greatly in 2001 to 2011 counties, the whole sequence is South of Jiangsu Subei Suzhou, and the development speed of each county area in the 10 years is the basis for the formation of the present situation in 2011. The spatial evolution of economic density and regional differences are beneficial to South of Jiangsu, Suzhou and North Jiangsu to formulate appropriate agricultural development strategies according to their own conditions, and provide the basis for the coordination of regional agricultural development and the formulation of agricultural industrial policies.
