【摘要】：大自然的生態(tài)系統(tǒng)可為人類提供生態(tài)服務(wù),對人類的生產(chǎn)生活起著重要的作用。然而隨著城市化和工業(yè)化的進程,人類在獲取自然服務(wù)的同時,也在改變著自然生態(tài)系統(tǒng)原有的結(jié)構(gòu),生態(tài)系統(tǒng)的服務(wù)功能在一定程度上被削弱,逐漸成為一種稀缺資源,并成為人們關(guān)注的熱點。針對區(qū)域生態(tài)服務(wù)價值時空分異規(guī)律的研究,可為區(qū)域的生態(tài)規(guī)劃和土地利用結(jié)構(gòu)調(diào)整提供科學(xué)依據(jù),對促進區(qū)域生態(tài)環(huán)境的建設(shè)和保護有著重要的理論意義和現(xiàn)實意義。本文選取晉城市域為研究區(qū)域,首先采用土地利用綜合動態(tài)度作為劃分晉城市域的指標,將其劃分為三個區(qū)域:城市核心區(qū)、城鄉(xiāng)交錯帶和城市外緣區(qū),并分別介紹了三個區(qū)域的特征及土地利用狀況。然后,對于非建設(shè)用地生態(tài)服務(wù)價值的評估,在謝高地的研究結(jié)果的基礎(chǔ)上進行區(qū)域修正;對于建設(shè)用地,采用間接市場法來進行評估。最后,分別對整個研究區(qū)域以及三個分區(qū)2001年和2010年的生態(tài)服務(wù)總價值的變化特點、基于各單項生態(tài)系統(tǒng)服務(wù)和基于各生態(tài)系統(tǒng)類型的生態(tài)服務(wù)價值分異規(guī)律作了分析,并采用空間自相關(guān)分析方法對研究區(qū)生態(tài)服務(wù)價值的空間集聚規(guī)律作了研究。研究表明:晉城市域的生態(tài)服務(wù)總價值從2001年到2010年呈減少趨勢,生態(tài)服務(wù)價值在各區(qū)域分異顯著這主要是生態(tài)用地在各區(qū)域的分布不均衡導(dǎo)致;對生態(tài)服務(wù)價值影響較大的地類是林地、耕地和建設(shè)用地,單項生態(tài)服務(wù)功能中廢物處理和水源涵養(yǎng)功能受城市化的影響退化較為顯著;從空間自相關(guān)性來看,研究區(qū)生態(tài)服務(wù)價值在空間分布上呈現(xiàn)顯著的正相關(guān)性,“高-高”區(qū)主要集中在城市外緣區(qū),“低-低”區(qū)主要集中在城市核心區(qū)和城鄉(xiāng)交錯帶,且兩個類型區(qū)呈進一步擴大趨勢,這是由于各區(qū)域在城市發(fā)展中的功能定位不同,發(fā)展方向就不同,土地利用結(jié)構(gòu)就有顯著差異,城市核心區(qū)注重城市發(fā)展,城市外緣區(qū)是生態(tài)涵養(yǎng)發(fā)展區(qū),而城鄉(xiāng)交錯帶處于過渡地帶。因此,在城市發(fā)展中要制定嚴格的生態(tài)規(guī)劃,合理規(guī)劃生態(tài)用地,促進城市建設(shè)與生態(tài)環(huán)境統(tǒng)籌協(xié)調(diào)發(fā)展。
[Abstract]:The ecosystem of nature can provide ecological services for human beings and play an important role in the production and life of human beings. However, with the process of urbanization and industrialization, human beings are acquiring natural services at the same time. It is also changing the original structure of the natural ecosystem, the service function of the ecosystem is weakened to a certain extent, and gradually become a scarce resource. The research on the temporal and spatial differentiation of regional ecological service value can provide scientific basis for regional ecological planning and land use structure adjustment. It has important theoretical and practical significance to promote the construction and protection of regional ecological environment. This paper selects Jincheng region as the research area, and firstly uses the comprehensive dynamic degree of land use as the index of dividing Jincheng region. It is divided into three regions: urban core area, urban-rural ecotone and urban outer edge area, and introduces the characteristics and land use status of the three regions respectively. Then, the evaluation of the value of non-construction land ecological services. On the basis of the research results of Xie Highland, the regional correction is carried out; For the construction land, the indirect market method is used to evaluate. Finally, the change characteristics of the total value of ecological services in the whole research area and the three sub-regions on 2001 and 2010 respectively. Based on each individual ecosystem service and each ecosystem type of ecosystem service value differentiation rule was analyzed. Spatial autocorrelation analysis was used to study the spatial agglomeration rule of ecological service value in the study area. The results showed that the total value of ecological service in Jincheng area decreased from 2001 to 2010. The value of ecological services varies significantly in different regions, which is mainly due to the uneven distribution of ecological land in different regions. Woodland, cultivated land and construction land are the most important factors affecting the value of ecological service. The waste disposal and water conservation function of single ecological service function are degraded by urbanization. From the spatial autocorrelation point of view, the value of ecological services in the study area showed a significant positive correlation in the spatial distribution, "high-high" area mainly concentrated in the outer edge of the city. The "low-low" areas are mainly concentrated in the urban core areas and the urban and rural ecotone, and the two types of areas show a trend of further expansion, which is due to the different functional orientation of each region in urban development, and the development direction is different. There are significant differences in land use structure, urban core areas focus on urban development, the outer edge of urban areas is ecological conservation and development areas, while the urban and rural ecotone is in the transition zone. In the course of urban development, strict ecological planning and rational planning of ecological land should be made to promote the coordinated development of urban construction and ecological environment.
