【摘要】 纵向岭谷区(Longitudinal Range-Gorge Region，LRGR)是连接我国以及欧亚大陆植物区系通过东南亚大陆与赤道热带相联系的唯一通道，同时是我国实施“澜沧江—湄公河次区域经济合作”以及“中国—东盟自由贸易区建设”等国家重大发展战略的热点地区。研究区内地形地貌复杂，区域内的温度、降水条件较适合植被生长，人口密度不大，原始生态系统保存较完好，植被覆盖度高，植被生产力巨大，生态脆弱性高，生态安全地位重要。本文在总结前人研究结果的基础上，确定了适合研究区特点的生态服务功能分析方法，以土地利用类型、净第一性生产力和植被覆盖数据为基础，遥感方法为手段，确定了生态系统服务功能价值的调整系数，得出纵向岭谷区1981年和2001年的生态系统服务功能价值，并从区域和县域两个尺度，时间和空间两个角度，研究该区生态系统服务功能价值的空间分布规律及其变化特点。本文对比了各行政区、主要流域以及流域内部不同区段的生态系统服务功能特点，确定纵向岭谷区生态系统服务功能价值存在着南高北低的空间分布规律，且在河流、山脊处有着不同的变化特点；通过分析不同人口密度和海拔梯度下生态系统服务功能的价值，得出生态系统服务功能价值有随人口密度和海拔升高而下降的规律；通过对比81年与2001年生态系统服务功能价值的变化，阐述了纵向岭谷区生态系统服务功能价值总体稳定、局部变化的规律。文章的最后对全文进行了归纳和总结，对有意义的问题展开讨论，提出了论文应改进的问题。更多还原

【Abstract】 Not only is LRGR(Longitudinal Range-Gorge Region) the sole corridor for floraexchanging from China, even southeast of Eurasia to the Equator, but also is the flourishingregion where China carry out the development strategy for GMS and Sino-ASEAN economycooperation. The topography and geomorphy is very sophisticated in LRGR. The temperatureand precipitation conditions are feasible to vegetation’s growth and the density of populationis mild. The original ecosystem is well saved and the vegetation coverage is very high whichcauses the large vegetation productivity. The ecosystem fragility is very high and the status ofecological security is very important.Based on the formerly results, we fix on the research methods of ecosystem servicewhich is suited the character of LRGR. The regulative coefficient is confirmed on the basis oflanduse type, net primary productivity and vegetation coverage by means of remote sensing.The ecosystem service values in 1981 and 2001 for this region are educed with it. The spatialrule and change character of ecosystem service is analyzed on regional and county scale. Thethesis compares the characters of ecosystem service in different district, main drainage basinand different segment in it, confirms the rules that the ecosystem service value is higher insouthern area than northern area and different characters along river and ridge. The ecosystemservice value is decreased regularly with the increasing of population density and elevationby compared analysis. The results of the ecosystem service values in 1981 and 2001 shows arule that ecosystem service value is steady for whole researched region and fluctuate in localarea in LRGR. In the last section, we generalize the whole thesis, discuss the significanceaspects and put forward the problem of the thesis.更多还原
