【摘要】：我国现代化进程中，城市化发展迅速,极大的推动国家和地区的社会经济发展，但在城市化迅速发展同时,粗放式的发展方式正在对人类社会与自然生态系统造成现实的破坏或潜在的威胁,对土地的经济价值尤其是潜在的生态服务价值不断地加大压力,也影响着我国的可持续发展。因此,研究城市化与生态环境间的关系,尤其是城市化与生态系统服务价值的耦合作用机制，以实现城市化和资源环境之间的协调，具有重大的理论和现实意义。鉴于此，本文在借鉴国外、国内相关研究成果基础上，立足于北部湾主要沿海城市-钦州市为研究对象，采用钦州市2000年、2005年和2010年三期TM遥感影像图、2005年的土地利用变更数据、地图和社会经济数据等资料，分析钦州市的土地利用变化情况，参考谢高地等人“中国不同陆地生态服务价值当量因子表”．结合广西地区具体情况，对钦州市的土地生态系统服务功能价值进行计算评估，并阐述钦州市土地生态系统服务功能价值的时空变异特征规律，并以是、SPSS、MINITAB、EXCEL等相关软件为辅助工具对生态服务价值变化与社会经济之间的关系做详细的分析。据此，构建城市化与生态服务价值耦合度指标体系，揭露两子系统的演变规律，测度协调发展度的演变，以探讨土地生态系统与城市化系统之间的耦合关系，并基于耦合规律上进行钦州市城市扩展模拟，为钦州城市的可持续发展提供空间决策和数据支持。本文得出以下几点结论： (1)对2000年到2010年间钦州市的土地利用变化分析。结果表明钦州市是一个农业为主导的城市，林地与耕地是主要的用地类型，其中林地比重最大。研究期间土地利用变化幅度最大的是林地，减少7.67%，主要转移到耕地和草地；其次主要变化地类有耕地、建设用地、水域等。 (2)对生态系统服务功能总价值的估算，并做研究期间生态服务价值变化分析。结果表明：土地生态系统服务价值变化总趋势是逐年递减的，其中林地生态系统产生的服务价值均最大，约占总价值的84.75%-89.07%，在各项服务功能中，生物多样性保护、水源涵养、气体调节产生的价值最大，三者合计约占总价值的44.97%-44.99%。 (3)基于STIRPAT模型的对钦州市生态系统服务价值变化的社会经济驱动因素分析。结果表明：人口的增长和城市化发展程度是影响钦州市生态系统服务价值和人均服务功能价值的最主要驱动力因素，其中城镇化率于生态系统服务总价值是正相关作用，而人均地区生产总值、人口、地区生产总值对生态服务系统总价值的影响为负相关作用。其次，对钦州市的城市化与生态服务价值耦合评价分析，，耦合评价结果显示:整体来说钦州市耦合发展类型还处于初级或初级到中级发展过渡阶段，是环境滞后型，2000年到2010年，钦州市城市化与生态服务价值的协调发展水平一直在稳定上升状态，耦合状态由失调衰退到勉强协调、初级协调与中级协调、再到良好协调。 (4)基于CLUE-S模型，对钦州市城市扩展模拟。研究反映钦州市城市扩展的方向和城市重心转移位置，及对生态服务价值的影响。可为钦州市城市化发展和可持续发展提供依据。
[Abstract]:In the process of modernization in China, the rapid development of city, promote the national and regional economic and social development, but in the rapid development of the city at the same time, the extensive mode of development is causing real damage or potential threat to human society and the natural ecological system of the land, the economic value of ecosystem services especially potential the value of increasing pressure, but also affect the sustainable development of our country. Therefore, study on the relationship between the city and the ecological environment of the city, especially the coupling mechanism and the value of ecosystem services, in order to realize the coordination between the city and the environment, is of great theoretical and practical significance.
In view of this, this paper draw on the basis of domestic and abroad, the relevant research results, based on the main North Bay coastal city - Qinzhou city as the research object, the Qinzhou city in 2000, 2005 and 2010 three period TM remote sensing images, the 2005 land use change data, maps and social economic data, land use change the analysis of Qinzhou City, Xie et al "reference China different land ecological service value equivalent factor table. Combined with the specific situation in Guangxi area of Qinzhou City, the land ecosystem service value evaluation, and expounds the characteristics of temporal and spatial variation of land ecosystem service value of Qinzhou City, and so, SPSS, MINITAB EXCEL, and other related software for the relationship between the auxiliary tool of the change of ecological service value and social economy to do a detailed analysis. Accordingly, the construction of city and ecological services value The coupling index system, reveal the evolution of two subsystems, the evolution of measure of the coordinated development degree, in order to investigate the coupling relationship between land ecosystem and city system, and based on the coupling laws of Qinzhou city urban expansion simulation, to provide decision-making and data support for the sustainable development of Qinzhou city.
This paper draws the following conclusions:
(1) to the analysis of land use change in 2010 years in Qinzhou city on 2000. The results show that the city of Qinzhou is a predominantly rural city, woodland and arable land is the main land use types, the largest proportion of woodland. During the study of land use change is the biggest forest, reduced by 7.67%, mainly transferred to cultivated land and grassland the second major change; type of arable land, construction land, water and so on.
(2) to estimate the total value of ecosystem service function, and analyze the change of ecological service value during the study period. The results showed that the general trend of land ecosystem service value change is decreasing year by year, the forest ecosystem service value is the largest, accounting for about 84.75%-89.07% of the total value, in each service function in water conservation of biodiversity conservation, gas regulation, produce the biggest value of three, the total of the total value of 44.97%-44.99%.
(3) analysis of the driving factors of the ecosystem service value in Qinzhou city changing social economy based on STIRPAT model. The results show that the degree of development of population growth and the city is the main driving force of ecosystem service value per capita and service value of Qinzhou City, the urbanization rate in the total value of ecosystem services positive correlation, and the per capita GDP, population, GDP to affect the total value of ecosystem services was negatively correlated.
Secondly, analysis of city and ecological service value of Qinzhou City coupling evaluation, the evaluation results show that the coupling of the whole Qinzhou City coupling development type is still in the primary or primary to secondary development is the transition stage, environment lag type, from 2000 to 2010, the level of coordinated development and ecological service value in Qinzhou city has been steadily rising state, coupling state by the recession to force coordination and coordination of primary intermediate coordination, to good coordination.
(4) based on the CLUE-S model, the simulation of urban expansion in Qinzhou is conducted. The research reflects the direction of urban expansion and the location of the city's gravity center and the impact on the ecosystem service value of Qinzhou. It can provide a basis for Qinzhou's urbanization development and sustainable development.
