【摘要】:文章圍繞表征基于解耦理論視角的土地利用變化與經(jīng)濟增長之間關(guān)系這一核心科學(xué)問題展開。將解耦理論和解耦分析引入到土地利用變化與經(jīng)濟增長之間的關(guān)系分析中,探討了土地利用變化與經(jīng)濟增長的解耦定義,改進了基于彈性分析的解耦評價方法,建立了土地利用變化與經(jīng)濟增長的解耦分析模型。文章在分別分析2002-2008年期間我國各省級區(qū)域(不包括港澳臺地區(qū))土地利用變化過程和經(jīng)濟變化過程的基礎(chǔ)上,,對我國農(nóng)用地變化與第一產(chǎn)業(yè)GDP、建設(shè)用地變化與非農(nóng)產(chǎn)業(yè)GDP以及未利用地投入變化與GDP總值之間關(guān)系的時空格局進行了研究。 研究表明:在2003-2008年期間,各地區(qū)土地利用變化與GDP變化的解耦與耦合程度存在時空差異性的同時存在主導(dǎo)類型或主要轉(zhuǎn)變趨勢的結(jié)論。(1)從農(nóng)用地大類來看:其中耕地變化與第一產(chǎn)業(yè)GDP關(guān)系存在從弱解耦狀態(tài)向弱耦合狀態(tài)轉(zhuǎn)變的趨勢;園地變化與第一產(chǎn)業(yè)關(guān)系存在從弱耦合向弱解耦轉(zhuǎn)變的態(tài)勢;林地變化與第一產(chǎn)業(yè)GDP關(guān)系由弱耦合向弱解耦轉(zhuǎn)變的態(tài)勢明顯;牧草地變化與第一產(chǎn)業(yè)GDP變化關(guān)系大多處于弱解耦狀態(tài),變化趨勢不明朗。其他農(nóng)用地變化與第一產(chǎn)業(yè)GDP關(guān)系存在由弱耦合狀態(tài)向弱解耦狀態(tài)轉(zhuǎn)變的態(tài)勢。(2)從建設(shè)用地大類來看,居民點和工礦用地變化、交通運輸用地變化以及水利設(shè)施用地變化與非農(nóng)產(chǎn)業(yè)GDP除了個別地區(qū)個別年份處于其他解耦與耦合關(guān)系外,其他大多數(shù)地區(qū)都處于弱耦合狀態(tài);(3)未利用地投入變化與GDP總值關(guān)系存在3種主要的轉(zhuǎn)變趨勢:由強解耦狀態(tài)向強耦合狀態(tài)轉(zhuǎn)變、由強解耦向狀態(tài)向弱耦合狀態(tài)轉(zhuǎn)變以及從強解耦狀態(tài)向弱解耦狀態(tài)轉(zhuǎn)變。
[Abstract]:This paper focuses on the core scientific problem of representing the relationship between land use change and economic growth from the perspective of decoupling theory. The decoupling theory and decoupling analysis are introduced into the analysis of the relationship between land use change and economic growth, the decoupling definition of land use change and economic growth is discussed, the decoupling evaluation method based on elastic analysis is improved, and the decoupling analysis model of land use change and economic growth is established. Based on the analysis of the process of land use change and economic change in various provincial regions (excluding Hong Kong, Macao and Taiwan) from 2002 to 2008, this paper studies the temporal and spatial pattern of the relationship between the change of agricultural land and the change of GDP, construction land in the primary industry and the GDP of non-agricultural industry, as well as the change of unused land input and the total value of GDP. The results show that from 2003 to 2008, there are temporal and spatial differences in the degree of decoupling and coupling between land use change and GDP change in each region, and there are dominant types or main transformation trends at the same time. (1) from the perspective of agricultural land categories, the relationship between cultivated land change and GDP in the primary industry tends to change from weak decoupling state to weak coupling state; The relationship between garden land change and primary industry changes from weak coupling to weak decoupling. The relationship between forest land change and GDP in primary industry is obvious from weak coupling to weak decoupling, and the relationship between forage land change and GDP in primary industry is mostly in a state of weak decoupling, and the changing trend is not clear. There is a trend that the relationship between other agricultural land changes and primary industry GDP changes from weak coupling state to weak decoupling state. (2) from the perspective of construction land, residential and industrial land change, transportation land change and water conservancy facilities land change and non-agricultural industry GDP are in a weak coupling state except in a few years in other decoupling and coupling relations; (2) from the construction land category, residential and industrial land change, transportation land change and water conservancy facilities land change and non-agricultural industry GDP are in a weak coupling state except in a few years; (3) there are three main transition trends between unused input change and GDP total value: from strong decoupling state to strong coupling state, from strong decoupling state to weak coupling state, and from strong decoupling state to weak decoupling state.
