中文摘要： 在贵州选择36个典型乡村地域，根据地貌、土地资源等空间组合格局的差异，结合社会经济背景，在岩溶高原面（普定后寨河、清镇王家寨）、岩溶峡谷（贞丰县花江峡谷）、自然保护区（荔波茂兰）根据内部差异选择典型乡村聚落及其人类活动地域，基于高精度的遥感影像和实地调查与实验分析，以乡村聚落为切入点，在自然村域及以下的乡村聚落尺度上，分析1960年代至2010年人口、聚落空间耦合动态过程，从微观层面评价人口、聚落空间动态演变对岩溶生态的影响力，分析典型乡村地域人口-聚落-生态耦合机制与模式，对乡村人口、聚落、生态空间优化调控的特征、动力机制、典型模式进行研究，构建岩溶山区乡村人口-聚落-生态地域耦合系统优化调控模式。旨在为岩溶山区美丽乡村建设、扶贫开发、生态建设和石漠化退化土地治理提供依据，促进农村地域转型升级与统筹发展。

英文摘要： To choose 36 typical villages in Guizhou Province, according to the differences of geographical spacial pattern based on topography and land resources, combined with the socio-economic background, selected typical rural settlements and human activities according to the internal differences in the Karst plateau surface (Houzhaihe in Puding County and Wangjiazhai in Qingzhen City),Karst Canyon (Huajiang Canyon in Zhenfeng County) and Nature Reserve (Maolan in Libo County).Based on high-precision remote sensing images,survey in the field and experimental analysis, taking rural settlement as the starting on the village scale (or the smaller scale), analyze the dynamic coupled process between the populationin and settlements in the village from the 1960s to 2010. Then evaluate the influence for the karst ecosystem from the micro-level dynamic coupled process between the populationin and settlements.Further analyze the coupling mechanism and mode of the typical rural regional Population-Settlement-Ecology.According to the characteristics,driving force and typical patterns of the optimization for spacial rural population, settlements and ecology, build the optimization modes of Karst mountainous rural Population-Settlement-Ecology geographical coupling system. Aimed at provide a basis for beautiful countryside construction, poverty alleviation and development, ecological construction and rocky desertification land management and promote the transformation and upgrading of the rural area and co-ordinate development in the Karst mountainous.
