【摘要】：人類發(fā)展和生存離不開土地,人類創(chuàng)造歷史的過程,也是對(duì)土地進(jìn)行改造的過程,隨著對(duì)土地的利用必然引起土地利用結(jié)構(gòu)的改變,進(jìn)而導(dǎo)致土地功能發(fā)生改變。進(jìn)入21世紀(jì)以來,隨著我國經(jīng)濟(jì)社會(huì)的發(fā)展、人口持續(xù)增長、工業(yè)化和城市化的快速推進(jìn),生態(tài)、生產(chǎn)和生活空間爭地現(xiàn)象凸顯,土地資源供需矛盾嚴(yán)峻。農(nóng)業(yè)用地是人類賴以生存的物質(zhì)基礎(chǔ),不僅具有重要的生產(chǎn)功能,還有重要的生態(tài)功能。人類對(duì)農(nóng)業(yè)用地利用過程中,往往只注重農(nóng)業(yè)用地的生產(chǎn)效應(yīng),忽視了其生態(tài)效應(yīng),造成了農(nóng)業(yè)用地的不合理使用,引發(fā)了諸多生態(tài)問題。黃驊市近年來經(jīng)濟(jì)快速發(fā)展,城市化水平不斷提升,但農(nóng)業(yè)仍然是該地區(qū)主導(dǎo)產(chǎn)業(yè)。該市生態(tài)脆弱且生態(tài)地位突出,同時(shí)農(nóng)業(yè)用地占比較大,在農(nóng)業(yè)生產(chǎn)的基礎(chǔ)上兼顧生態(tài),提高區(qū)域農(nóng)業(yè)用地利用多功能效應(yīng),具有重要意義。本文通過構(gòu)建農(nóng)業(yè)用地利用效應(yīng)評(píng)價(jià)指標(biāo)體系,對(duì)黃驊市農(nóng)業(yè)用地利用效應(yīng)進(jìn)行評(píng)價(jià),并進(jìn)行分區(qū),為黃驊市土地合理利用提供理論基礎(chǔ)。論文內(nèi)容主要包括:(1)通過構(gòu)建黃驊市農(nóng)業(yè)用地利用效應(yīng)評(píng)價(jià)指標(biāo)體系,通過測算農(nóng)業(yè)用地利用效應(yīng)分值、效應(yīng)實(shí)現(xiàn)率和動(dòng)態(tài)變化度,對(duì)黃驊市2003-2012年農(nóng)業(yè)用地利用生產(chǎn)效應(yīng)和生態(tài)效應(yīng)動(dòng)態(tài)變異性進(jìn)行分析。結(jié)果顯示:黃驊市農(nóng)業(yè)用地生產(chǎn)效應(yīng)呈現(xiàn)快速增長趨勢,生態(tài)效應(yīng)呈現(xiàn)緩慢退化趨勢。從農(nóng)業(yè)用地利用效應(yīng)實(shí)現(xiàn)率來看,黃驊市農(nóng)業(yè)用地利用生產(chǎn)效應(yīng)和生態(tài)效應(yīng)都為中度可持續(xù)水平,有待進(jìn)一步提高。(2)以鄉(xiāng)鎮(zhèn)為基本單元,運(yùn)用綜合指數(shù)法和自然斷點(diǎn)法,分析2012年黃驊市農(nóng)業(yè)用地利用效應(yīng)空間分布特征,結(jié)果顯示黃驊市農(nóng)業(yè)用地利用效應(yīng)呈現(xiàn)一定的集聚特征。其中生產(chǎn)效應(yīng)較好的區(qū)域主要集中在遠(yuǎn)離海邊的市域西部,生態(tài)效應(yīng)較好的區(qū)域主要集中在市域東北部,空間集聚的特點(diǎn)可以為黃驊市土地利用功能分區(qū)提供借鑒。(3)運(yùn)用灰色關(guān)聯(lián)分析模型及阻力模型,對(duì)制約黃驊市農(nóng)業(yè)用地利用生產(chǎn)效應(yīng)和生態(tài)效應(yīng)的限制因素進(jìn)行定量分析,得出近年來,黃驊市生產(chǎn)效應(yīng)的土地制約因素主要是耕地質(zhì)量、自然災(zāi)害和農(nóng)田灌溉面積,生態(tài)效應(yīng)的主要制約因素為森林覆蓋率,人均生態(tài)用地面積和水域用地比例。運(yùn)用疊置法將黃驊市分為生態(tài)、生產(chǎn)、生活三個(gè)大區(qū)。并結(jié)合制約因素,提出了土地利用功能分區(qū)建設(shè)的建議。為未來黃驊市農(nóng)業(yè)用地的合理利用、可持續(xù)、協(xié)調(diào)發(fā)展提供理論借鑒。
[Abstract]:Human development and survival can not be separated from land. The process of human creation of history is also the process of land transformation. With the use of land, the structure of land use will be changed, and then the land function will be changed. Since the beginning of the 21st century, with the development of economy and society, the continuous increase of population, the rapid advance of industrialization and urbanization, the phenomenon of land competition between ecology, production and living space has become prominent, and the contradiction between supply and demand of land resources is severe. Agricultural land is the material basis of human survival, not only has important production function, but also important ecological function. In the process of agricultural land use, people usually only pay attention to the production effect of agricultural land, ignore its ecological effect, cause irrational use of agricultural land, and cause many ecological problems. Huanghua has developed rapidly in recent years, but agriculture is still the leading industry in Huanghua. The ecology of the city is fragile and the ecological status is prominent, and the agricultural land occupies a large proportion. It is of great significance to give consideration to ecology on the basis of agricultural production and to improve the multifunctional effect of regional agricultural land use. By constructing the evaluation index system of agricultural land use effect, this paper evaluates the agricultural land use effect in Huanghua and divides it into different areas, which provides a theoretical basis for the rational use of land in Huanghua. The main contents of this paper are as follows: (1) by constructing the evaluation index system of agricultural land use effect in Huanghua, the paper calculates the score of agricultural land use effect, the rate of effect realization and the degree of dynamic change. The dynamic variability of agricultural land use effects and ecological effects in Huanghua from 2003 to 2012 was analyzed. The results showed that the effect of agricultural land production in Huanghua showed a rapid growth trend, and the ecological effect showed a slow degradation trend. According to the realization rate of agricultural land use effect, both the production effect and ecological effect of agricultural land use in Huanghua are moderately sustainable, which need to be further improved. (2) taking villages and towns as the basic unit, the comprehensive index method and the natural breakpoint method are used. The spatial distribution characteristics of agricultural land use effect in Huanghua City in 2012 were analyzed. The results showed that the agricultural land use effect in Huanghua City showed a certain agglomeration feature. Among them, the areas with better production effects are mainly concentrated in the western part of the city, which is far from the seaside, and the areas with better ecological effects are mainly concentrated in the northeast of the city area. The characteristics of spatial agglomeration can be used for reference for land use functional zoning in Huanghua. (3) using grey relational analysis model and resistance model, quantitative analysis is carried out on the limiting factors that restrict the production effect and ecological effect of agricultural land use in Huanghua. In recent years, the land restriction factors of production effect in Huanghua are mainly cultivated land quality, natural disaster and farmland irrigation area, and the main restricting factors of ecological effect are forest coverage, per capita ecological land area and water area proportion. Huanghua City is divided into three regions: ecology, production and life. Combined with the restrictive factors, the suggestions of land use function zoning construction are put forward. It provides theoretical reference for the rational utilization, sustainable and coordinated development of agricultural land in Huanghua in the future.
