【摘要】：以西部山區(qū)重慶鄉(xiāng)村空間為研究對象,構(gòu)建鄉(xiāng)村空間多功能評價(jià)指標(biāo)體系,將鄉(xiāng)村空間多功能劃分為農(nóng)業(yè)生產(chǎn)功能、經(jīng)濟(jì)發(fā)展功能、生態(tài)保育功能、生態(tài)穩(wěn)定性功能,社會保障居住家園功能五種子功能,采用熵權(quán)法定量核算2013年全市鄉(xiāng)村空間功能值,運(yùn)用GIS技術(shù)和Dagum基尼系數(shù)刻畫重慶市不同地區(qū)鄉(xiāng)村空間功能值地區(qū)差異特征,并劃分了重慶市鄉(xiāng)村空間多功能類型,研究結(jié)果表明:(1)山地型鄉(xiāng)村地形復(fù)雜,景觀類型多樣,功能也極具多樣性,研究區(qū)鄉(xiāng)村空間除了生態(tài)穩(wěn)定性功能外,其他各功能值具有顯著的空間分異特征,有明顯的空間集聚性。(2)Dagum基尼系數(shù),是一種有效的技術(shù)方法,能夠更為深入地刻畫研究區(qū)鄉(xiāng)村空間功能值地區(qū)間差異及區(qū)內(nèi)差異特征�；嵯禂�(shù)測算及其分解結(jié)果顯示,地區(qū)間差距是總體差距的主要來源,其貢獻(xiàn)率都超過50%。(3)根據(jù)鄉(xiāng)間空間多功能分布的差異性及山地鄉(xiāng)村的特點(diǎn)和山區(qū)生態(tài)環(huán)境的脆弱性,將研究區(qū)鄉(xiāng)村空間劃分為農(nóng)業(yè)生產(chǎn)-經(jīng)濟(jì)發(fā)展型,農(nóng)業(yè)生產(chǎn)-人居生活型,人居生活-社會保障型,人居生活-經(jīng)濟(jì)發(fā)展型,水源涵養(yǎng)生態(tài)保育型,生態(tài)保育-經(jīng)濟(jì)發(fā)展型,生態(tài)保育-農(nóng)業(yè)生產(chǎn)型,土壤保持生態(tài)保護(hù)型8種功能類型,能較好地體現(xiàn)地域特色,為科學(xué)健康的開發(fā)利用山地鄉(xiāng)村空間土地資源提供有益借鑒,有利于區(qū)域協(xié)調(diào)可持續(xù)發(fā)展。
[Abstract]:Taking Chongqing rural space in western mountainous area as the research object, the multi-function evaluation index system of rural space is constructed. The multi-function of rural space is divided into agricultural production function, economic development function, ecological conservation function and ecological stability function.The five kinds of functions of social security residential homes were calculated by entropy weight method in 2013, and the differences of rural spatial function values in different areas of Chongqing were characterized by GIS technique and Dagum Gini coefficient.The multi-functional types of rural space in Chongqing are divided. The results show that the mountainous rural areas have complex terrain, various landscape types and extremely diverse functions. Besides the ecological stability function, the rural space in the study area is characterized by ecological stability.The other function values have distinct spatial differentiation characteristics and obvious spatial agglomeration. Dagum Gini coefficient is an effective technical method, which can more deeply describe the regional differences and regional differences of rural spatial function values in the study area.The results of Gini coefficient and its decomposition show that the gap between regions is the main source of the overall disparity, and its contribution rate is over 50%.) according to the difference of spatial multifunctional distribution in rural areas, the characteristics of mountainous villages and the fragility of ecological environment in mountainous areas, the Gini coefficient is the main source of the gap.The rural space of the study area is divided into three types: agricultural production-economic development type, agricultural production-human settlements type, human settlements life-social security type, human living-economic development type, water conservation ecological conservation type, ecological conservation-economic development type.Ecological conservation-agricultural production type, soil conservation ecological protection type 8 functional types, can better reflect the regional characteristics, for the scientific and healthy development and utilization of rural land resources in mountainous areas, provide a useful reference.It is conducive to regional coordinated and sustainable development.
