【摘要】：土地資源是人類賴以生存的自然資源和物質(zhì)基礎(chǔ),同時也是區(qū)域社會經(jīng)濟建設(shè)和發(fā)展最基本的需求保障。但是,土地資源的承載能力在一定的空間和時間范圍內(nèi)是有限的。近年來,隨著臨安市城市化和工業(yè)化進程的加速,人口日益增多,建設(shè)用地需求量劇增,有限的土地供給和無限的建設(shè)用地需求之間的矛盾十分突出。再加上城市擴張過程中交通、能源、水利、環(huán)保等基礎(chǔ)設(shè)施用地需求量加大,建設(shè)需求呈現(xiàn)快速增長趨勢,造成區(qū)域范圍內(nèi)人地矛盾的日益加劇。因此,從土地資源的可持續(xù)利用角度出發(fā),評價目前臨安市土地資源承載力狀況十分必要。 本文在總結(jié)國內(nèi)外相關(guān)理論和方法的基礎(chǔ)上,結(jié)合臨安市自身的區(qū)域特點,構(gòu)建臨安市土地資源承載力評價的指標(biāo)體系。該體系結(jié)構(gòu)是從生態(tài)環(huán)境承載、社會承載、經(jīng)濟承載三個支撐子系統(tǒng)出發(fā),選取了22個評價指標(biāo),運用極差變換法、均方差決策法和變異系數(shù)法以及綜合計算法對臨安市2005-2012年土地資源承載力的動態(tài)變化情況進行了評價研究。研究結(jié)果表明：(1)從綜合承載力上來看,臨安市土地資源承載力從2005到2012年有很大提高,總體趨勢上雖然呈曲折上升,但增長速度較快,綜合承載力不斷提高。生態(tài)環(huán)境、社會和經(jīng)濟三個子系統(tǒng)的承載能力也有較大程度的提高,其中生態(tài)環(huán)境承載力的不斷提升對于提高臨安市土地綜合承載力的貢獻最大；(2)從系統(tǒng)內(nèi)部來看,各支撐子系統(tǒng)間協(xié)調(diào)程度不一。其中生態(tài)環(huán)境承載能力增長較快,增長幅度最大,超過社會承載和經(jīng)濟承載,與生態(tài)環(huán)境承載相適應(yīng)的社會和經(jīng)濟的承載水平有待進一步提高；(3)土地綜合承載力的高低主要取決于兩大因素：一是各承載子系統(tǒng)的自身狀況；二是各子系統(tǒng)之間的協(xié)調(diào)程度。最后根據(jù)以上結(jié)論,本文從加強生態(tài)環(huán)境保護、加快經(jīng)濟發(fā)展和政策引導(dǎo)等方面提出了提高臨安市土地綜合承載力的建議。
[Abstract]:Land resources are not only the natural resources and material foundation on which human beings depend for survival, but also the most basic demand guarantee for the construction and development of regional society and economy. The carrying capacity of land resources is limited in a certain space and time. In recent years, with the acceleration of urbanization and industrialization in Linan City, the population is increasing day by day, and the demand for construction land is increasing sharply. The contradiction between the limited land supply and the unlimited demand for construction land is very prominent. In addition, during the process of urban expansion, the demand for land for infrastructure such as transportation, energy, water conservancy and environmental protection has increased, and the demand for construction has shown a rapid growth trend. Therefore, it is necessary to evaluate the carrying capacity of land resources in Linan from the perspective of sustainable utilization of land resources. On the basis of summarizing the relevant theories and methods at home and abroad and combining the regional characteristics of Linan City, this paper constructs an index system for evaluating the carrying capacity of land resources in Linan City. Starting from the three supporting subsystems of economic carrying capacity, 22 evaluation indexes are selected, and the range transformation method is used. The dynamic change of land resources carrying capacity in Linan City from 2005 to 2012 was evaluated by means of mean-variance decision making method, coefficient of variation method and comprehensive calculation method. The results show that: 1) from the perspective of comprehensive bearing capacity, From 2005 to 2012, the carrying capacity of land resources in Linan City has been greatly improved. Although the overall trend is twists and turns, the growth rate is relatively fast, and the comprehensive carrying capacity is constantly improving. The bearing capacity of the three subsystems of society and economy has also been greatly improved, among which the continuous improvement of the ecological environment carrying capacity has the greatest contribution to the improvement of the comprehensive bearing capacity of the land in Lin'an.) from the point of view of the internal system, The degree of coordination among the supporting subsystems is different. Among them, the carrying capacity of the ecological environment has increased rapidly, with the largest growth range, which exceeds the social and economic carrying capacity. The level of social and economic bearing capacity corresponding to ecological environment should be further improved. (3) the comprehensive bearing capacity of land depends mainly on two factors: first, the condition of each bearing subsystem; Finally, according to the above conclusions, this paper puts forward some suggestions to improve the comprehensive carrying capacity of land in Linan from the aspects of strengthening ecological environment protection, speeding up economic development and policy guidance.
