【摘要】：隨著國家西部開發(fā)戰(zhàn)略深入實(shí)施,西南通道建設(shè)加快,大力推動(dòng)了西南經(jīng)濟(jì)的發(fā)展,德宏經(jīng)濟(jì)發(fā)展也面臨著重大挑戰(zhàn)。經(jīng)濟(jì)開發(fā)活動(dòng)的不斷擴(kuò)張,德宏州土地利用受自然、社會和經(jīng)濟(jì)等各方面因素的影響不斷出現(xiàn)新的問題,土地利用的社會、經(jīng)濟(jì)和社會產(chǎn)出效益都在不斷變化。為了適應(yīng)經(jīng)濟(jì)發(fā)展新形勢,首先要對德宏州土地利用效益有深入而具體的了解,因此對其進(jìn)行土地利用效益評價(jià)顯得十分重要。本文結(jié)合兩次全國性土地調(diào)查的數(shù)據(jù)結(jié)果,在分析德宏州土地利用結(jié)構(gòu)變化的基礎(chǔ)上,對德宏州進(jìn)行土地利用效益評價(jià)和變化分析,研究成果可以為科學(xué)編制德宏州及其各縣市土地利用總體規(guī)劃,提高全州土地利用綜合效益,推進(jìn)德宏州及西南邊疆地區(qū)土地的可持續(xù)利用提供基礎(chǔ)依據(jù)。本文以德宏州為研究對象,以德宏州兩次全國土地調(diào)查的1996年和2013年的數(shù)據(jù)為基礎(chǔ),在分析德宏土地利用現(xiàn)狀結(jié)構(gòu)的基礎(chǔ)上,分別以德宏州及所轄5個(gè)縣(市)作為評價(jià)單元,選取14個(gè)評價(jià)指標(biāo),建立了德宏州土地利用綜合效益評價(jià)指標(biāo)體系。在此過程中運(yùn)用德爾菲法和層次分析法(運(yùn)用MATLAB軟件)進(jìn)行賦權(quán),采用綜合指數(shù)效益模型進(jìn)行綜合評價(jià),對1996年和2013年德宏州及所轄5個(gè)縣(市)土地利用的生態(tài)、經(jīng)濟(jì)、社會和綜合效益進(jìn)行了評價(jià)分析。研究結(jié)果表明:1、通過德宏2013年和1996年的土地利用結(jié)構(gòu)對比,在這17年間德宏州耕地面積呈減少態(tài)勢,耕地保護(hù)形勢嚴(yán)峻;德宏正處于城鎮(zhèn)化、工業(yè)化加速發(fā)展階段,其建設(shè)用地面積增加快速,其中城鎮(zhèn)村及工礦用地和交通運(yùn)輸用地均呈大幅度增長�？傮w而言,農(nóng)用地被占用較為嚴(yán)重,土地利用結(jié)構(gòu)有待優(yōu)化。2、從州級土地利用效益評價(jià)結(jié)果來看,德宏州17年間土地利用綜合效益指數(shù)值增加了0.2809,增幅顯著。其中,經(jīng)濟(jì)效益指數(shù)值增加了0.1816,增幅明顯;生態(tài)效益增幅平緩,其指數(shù)值僅增加了0.0112;社會效益增幅居中,其指數(shù)值增加了0.0881。3、從縣級尺度的土地利用效益評價(jià)結(jié)果看,德宏州所轄5個(gè)縣(市)的土地利用綜合效益均有所提升,但17年間各縣(市)經(jīng)濟(jì)、社會、生態(tài)效益的變化趨勢差異較大。綜合效益指數(shù)值增幅最大的是梁河縣,其綜合效益指數(shù)值增加了0.1347;綜合效益指數(shù)值增幅最小的是隴川縣,其綜合效益指數(shù)值僅增加了0.0198。其中,經(jīng)濟(jì)效益指數(shù)值增幅最大的是芒市,其經(jīng)濟(jì)效益指數(shù)值增加了0.0482;盈江縣、梁河縣增幅位居其次。生態(tài)效益指數(shù)值增幅最大的是梁河縣,其生態(tài)效益指數(shù)值增加了0.0194;生態(tài)效益指數(shù)值下降最為明顯的是隴川縣,其生態(tài)效益指數(shù)值下降了0.0454。社會效益指數(shù)值增幅最大的是盈江縣,其社會效益指數(shù)值增加了0.0890;社會效益指數(shù)值增幅最小的是隴川縣,其社會效益指數(shù)值僅增加了0.0292。4、目前,德宏土地利用中存在的主要問題是:建設(shè)用地占用壩區(qū)耕地嚴(yán)重,壩區(qū)優(yōu)質(zhì)耕地亟需保護(hù);耕地后備資源有限;土地利用粗放,尤其城鄉(xiāng)建設(shè)用地集約化程度整體偏低;未來建設(shè)用地供求矛盾日益增大。5、針對上述主要問題,本文提出的相應(yīng)對策是:嚴(yán)格保護(hù)耕地,尤其是守衛(wèi)壩區(qū)優(yōu)質(zhì)耕地和永久基本農(nóng)田;走山壩結(jié)合的城鎮(zhèn)化道路,積極推進(jìn)城鎮(zhèn)和工業(yè)建設(shè)用地上山戰(zhàn)略的實(shí)施;調(diào)整和優(yōu)化現(xiàn)有土地利用結(jié)構(gòu),努力提高土地利用集約程度;保護(hù)自然生態(tài)資源,重視生態(tài)環(huán)境保護(hù),建設(shè)生態(tài)德宏;因地制宜,統(tǒng)籌兼顧,大力推進(jìn)各縣(市)土地利用協(xié)調(diào)發(fā)展;完善土地利用管理手段,提高土地利用管理水平,促進(jìn)土地可持續(xù)利用。
[Abstract]:With the deepening implementation of the national western development strategy and the acceleration of the construction of the southwest corridor, the development of the southwest economy has been greatly promoted, and the economic development of Dehong is also facing major challenges. In order to adapt to the new situation of economic development, it is necessary to have a thorough and concrete understanding of land use efficiency in Dehong Prefecture, so it is very important to evaluate land use efficiency. On the basis of structural change, land use benefit evaluation and change analysis are carried out in Dehong Prefecture. The research results can provide the basis for scientific compilation of overall land use planning of Dehong Prefecture and its counties and cities, improvement of comprehensive land use efficiency and promotion of sustainable land use in Dehong Prefecture and southwestern border areas. Based on the data of two national land surveys in Dehong Prefecture in 1996 and 2013, and on the basis of analyzing the present structure of land use in Dehong prefecture, the evaluation index system of comprehensive land use benefit in Dehong Prefecture was established by taking Dehong Prefecture and five counties (cities) under its jurisdiction as evaluation units and selecting 14 evaluation indexes. In this paper, Delphi method and analytic hierarchy process (MATLAB software) are used to empower, and comprehensive index benefit model is used to evaluate the ecological, economic, social and comprehensive benefits of land use in Dehong Prefecture and its five counties (cities) in 1996 and 2013. In the 17 years, the cultivated land area in Dehong Prefecture was decreasing, and the cultivated land protection situation was grim; Dehong was in the stage of urbanization and accelerated industrialization, and its construction land area increased rapidly, among which urban village, industrial and mining land and transportation land showed a large increase. From the results of land use efficiency evaluation at the state level, the comprehensive benefit index of land use in Dehong Prefecture increased by 0.2809, with a significant increase of 0.1816. The ecological benefit increased gently, and the social benefit increased by 0.0112. The index value increased by 0.0881.3. According to the results of land use benefit evaluation at County level, the comprehensive land use benefit of the five counties (cities) under the jurisdiction of Dehong prefecture has been improved, but the trend of economic, social and ecological benefit varies greatly in the past 17 years. The value of comprehensive benefit index increased by 0.1347; Longchuan County had the smallest increase, and the value of comprehensive benefit index increased by 0.0198. Among them, Mang City had the largest increase, and its economic benefit index value increased by 0.0482; Yingjiang County and Lianghe County had the second largest increase. The index value of ecological benefit increased by 0.0194; the index value of ecological benefit decreased most obviously in Longchuan County, and its index value decreased by 0.0454. At present, the main problems in Dehong's land use are as follows: the construction land occupies the cultivated land of dam area seriously, and the high-quality cultivated land in dam area is in urgent need of protection; the reserve resources of cultivated land are limited; the land use is extensive, especially the degree of urban and rural construction land intensive is on the low side as a whole; the contradiction between supply and demand of construction land is increasing day by day. 5 The corresponding countermeasures proposed in this paper are: strictly protect cultivated land, especially the high-quality cultivated land and permanent basic farmland in the dam area; take the road of urbanization combining mountain and dam, actively promote the implementation of the strategy of urban and industrial construction land uphill; adjust and optimize the existing land use structure, and strive to improve the intensity of land use; protect the natural ecology. Resources should be paid attention to ecological environment protection and ecological Dehong should be constructed. The coordinated development of land use among counties (cities) should be vigorously promoted according to local conditions. Means of land use management should be improved to improve the level of land use management and promote sustainable land use.
