In order to grasp the urban system processes and evolution pattern of hunan province comprehensively, this article has made further discussion on its structure characteristic : through regression analysis, graph analysis and statistics analysis of the time series data and cross sections data, by combining with the fractal theory, we induce the following conclusion : the hierarchical size structure presents the law of the primate city, the rank - size rule and pyramid structure characteristic, but it also has the insufficient development problem of the high hierarchical size city. by using the gravitation model, we found out that the economy relation intensity among those main cities is weak while the structure is loose. based on the urban layer system of economic development level and industrial structure evolution of the cities in hunan province, this article then induces the function combination among the five urban agglomerations in hunan province
為全面把握湖南城市體系的運演規律，本文對其結構特徵作了進一步的探討:通過時序數據和截面數據的回歸分析、圖表分析和統計分析，結合分形理論，得出了其等級規模結構分佈呈現出首位分佈、位序?規模分佈和金字塔結構特徵，以及存在著高層次城市發展不足的問題;運用場引力模型發現該省主要城市間的經濟聯系強度較弱、結構鬆散，在歸納出該省城市經濟發展水平的層次體系、產業結構演變的基礎上，導出了該省城市體系的五大城市群職能組合;結合空間結構體系、路網交通條件和經濟發展狀況，對該省城市空間分佈狀態進行了定性分析，研究表明該省總體上處于極化階段，各個具體區域，分佈階段不一，差異較大。 -
The spatial structure of 13 cities ( counties ) shows obvious fractal characters, axis characters. 13 cities ( counties ) mainly distribute on jingguang, xiangqian trunk railway and shichang, zhegan - licha railway line and 319 national highway and jingzhu expressway, which form the axes where the industries of changsha - zhuzhou - xiangtan urban agglomeration centralize on
研究結果表明，長株潭城市群13個市、縣的空間結構顯示出分形特徵，且表現為明顯的軸線特徵，分佈在京廣鐵路、湘黔鐵路、石長鐵路、浙贛一醴茶鐵路及319國道和京珠高速等主要交通軸線上，是長株潭城市群產業集中分佈的主要軸線。 -
At last, according to relationship among the average fractal dimension of annual breeding time precipitation, accumulated temperature and crops yield of heilongjiang province, the climatic division and the comprehensive climatic division of precipitation, accumulated temperature of 79 counties and cities were divided by fractal dimension of precipitation and accumulated temperature. at same time, divisional results were combined with the information system. proved that divisional results accorded with fact, the fractal method deeply reflected complicated changes on precipitation and accumulated temperature of heilongjiang provinc and information system had convenient advantage in graphic display
最後，根據黑龍江省歷年生育期降水、積溫的平均分維與作物產量的關系，對79個縣市按生育期降水、積溫分維的大小分別進行了生育期降水、積溫的氣候區劃，以及綜合區劃，將區劃結果與信息系統有機結合，並證明區劃結果符合實際，分形方法更深刻、全面地反映了降水、積溫的復雜變化，信息系統方便的圖形顯示優點，該區劃結果對原黑龍江省的氣候區劃是有益的補充。
