【摘要】：隨著人類社會與科學研究領(lǐng)域的共同發(fā)展,人類逐漸意識到生態(tài)環(huán)境與社會進步聯(lián)系緊密,平衡經(jīng)濟發(fā)展、環(huán)境保護與人類進步三者的關(guān)系以保證我國的可持續(xù)發(fā)展是未來研究的重點方向。土地利用方式是否合理直接影響到生態(tài)環(huán)境的好壞,本文以長沙市岳麓區(qū)蓮花鎮(zhèn)為研究對象。分析了研究區(qū)的土地利用變化、生態(tài)系統(tǒng)服務(wù)價值變化情況以及二者的相關(guān)關(guān)系。并根據(jù)研究區(qū)各行政村土地生態(tài)質(zhì)量的優(yōu)劣程度不同,對其進行等級劃分,提出合理的土地利用結(jié)構(gòu)調(diào)整建議,以期為研究區(qū)的可持續(xù)發(fā)展提供理論依據(jù)。研究結(jié)果表明：(1)研究區(qū)林地、水域、草地和未利用地屬于原生生態(tài)用地,耕地和園地屬于半人工生態(tài)用地,水利設(shè)施用地以及草地中的綠化用地屬于人工生態(tài)用地,建設(shè)用地屬于非生態(tài)用地。(2)研究期間耕地、園地、未利用地面積減少,未利用地減少速度最快；林地、水域及水利設(shè)施用地、建設(shè)用地面積增加,建設(shè)用地增長速度最快。(3)2003-2013年,蓮花鎮(zhèn)的生態(tài)系統(tǒng)服務(wù)總價值呈現(xiàn)出持續(xù)減少的趨勢,共減少了1363.9萬元,其中水源涵養(yǎng)服務(wù)功能的價值量減少最快；五村開展“土地綜合整理”項目后導致研究區(qū)總ESV(生態(tài)系統(tǒng)服務(wù)價值)下降,桐木村是導致這一變化的熱點區(qū)域。(4)通過變差貢獻率分析得到,林地、水域和水利設(shè)施用地面積的變化趨勢與研究區(qū)總ESV的變化趨勢相反,對維持研究區(qū)生態(tài)系統(tǒng)的健康做正貢獻,同理耕地、園地、建設(shè)用地和未利用地做負貢獻；通過灰色關(guān)聯(lián)度分析,得到建設(shè)用地和林地面積的變化對研究區(qū)總ESV的變化影響最為強烈。(5)運用SPSS軟件對不同土地類型面積的相互轉(zhuǎn)化進行相關(guān)性分析得到,研究區(qū)的土地利用方式逐漸由以耕地為主向以經(jīng)濟用地為主轉(zhuǎn)變；運用SPSS軟件對影響研究區(qū)生態(tài)系統(tǒng)服務(wù)價值的13個社會經(jīng)濟指標進行主成分提取,將其歸納為三大類,即經(jīng)濟因子、人口因子和城市化因子。社會經(jīng)濟因子值越高,生態(tài)系統(tǒng)服務(wù)價值越低,說明研究區(qū)社會經(jīng)濟的快速發(fā)展是以犧牲生態(tài)環(huán)境為代價的。(6)采用總分頻率曲線法將研究區(qū)的17個行政村根據(jù)其土地生態(tài)質(zhì)量水平不同,分為四個等級,即土地生態(tài)質(zhì)量良好區(qū)、土地生態(tài)質(zhì)量較好區(qū)、土地生態(tài)質(zhì)量一般區(qū)和土地生態(tài)質(zhì)量較差區(qū)。
[Abstract]:With the common development of human society and the field of scientific research, people gradually realized that ecological environment and social progress closely, balanced economic development, the relationship between environmental protection and human progress of the three in order to ensure the sustainable development of our country is one of the key research directions in the future. Land use is reasonable or not directly affects the quality of the ecological environment in this paper. In the lotus town of Yuelu District city as the research object. Changsha analysis of land use change in the study area. The correlation between the changes of ecosystem service value and the two. And according to the extent of the study area of each administrative village land ecological quality is different, its classification, the adjustment of land use structure of reasonable proposals to provide a theoretical basis for the sustainable development of the study area. The results show that: (1) the study area waters, forest land, grassland and unused land belonging to the original ecological use Land, farmland and garden is a semi artificial ecological land, water conservancy facilities land and grassland in the green land belongs to artificial ecological land, construction land belongs to the non ecological land. (2) during the study period, the garden land and unused land decreased, unused land decreased fastest; forest land with the increase of water and water conservancy facilities, construction land area, construction land is the fastest growth. (3) 2003-2013 years, ecosystem services value of lotus town showed a decreasing trend, a total reduction of 13 million 639 thousand yuan, of which the value of water conservation function to reduce the fastest five village to carry out land; comprehensive consolidation "project resulted in the total ESV study area (ecosystem service value) decreased, Paulownia village is a hotspot that led to this change. (4) through the analysis of the contribution rate of variation, woodland, and the change trend of the study area by area waters and water conservancy facilities The general trend of ESV on the contrary, for the maintenance of ecosystem health in the study area are similarly contribution, cultivated land, garden land and unused land have negative contribution to construction; through grey correlation analysis, get the construction of the total ESV of the study area change of land and forest land area is most intense. (5) using SPSS software on the mutual transformation of different types of land area by correlation analysis, the study area land use the cultivated land to economic land change; by using SPSS software to affect the value of ecosystem services in the study area of the 13 Social and economic indicators of principal component extraction, which can be classified into three that is, economic factor, population factor and factor of city social economic factors. The higher the value, the value of ecosystem services is lower, that of the rapid development of social economy is sacrificing ecological environment (6) using the total score frequency curve method, 17 administrative villages in the study area were divided into four levels according to their land ecological quality level, namely, the good land ecological quality area, the better land ecological quality area, the general land ecological quality area and the poor land ecological quality area.
