Five factors as the motive force for the tourist development in guizhou karst terrain were proposed . the growth pole of tourist economy in guizhou karst terrain was defined in the initial use of the shift - share analysis . in the end , a tourism economic circle of guizhou karst terrain was constructed , as guiyang , anshun and zunyi being the first - level tourist circle , high graded roads as well as national and provincial highways being the axis , and the kernel layer , hinterland layer , radiation layer and extension layer of the tourist economy being the spatial radius 通过对区域旅游整合模式的概述,结合贵州省情,选择了适合贵州喀斯特地区旅游业发展的“点-轴-圈”模式;提出了贵州喀斯特地区旅游发展的五个动力因子;首次采用“份额?偏离分析法”确定出贵州喀斯特地区旅游经济增长极;最后以贵阳、安顺、遵义为一级旅游中心,以高等级公路、国道、省道为轴线,以旅游经济的核心层、腹地层、辐射层和扩展层为空间半径,构建出贵州喀斯特地区旅游经济圈。
Karst areas have a most typical frail ecological environment and complex human - land system . its frailty is displayed in such distinct features as the strong sense of environmental mutation , low environmental capacity , limited ability of standing disasters , poor stability , sharp ecological competition and small quantity of living things 喀斯特地区具有一类最典型的脆弱生态环境和复杂的人地系统，其脆弱性表现出环境变异敏感度高、环境容量低、承灾能力低、稳定性差、生态系统竞争程度高、生物量小等鲜明特征。
Through the study on the producing and living of the relationship human beings and geography of karst environment , the paper holds the point of view that karst culture is the outcomes of local people ' s producing and living creation and their passing from one generation to another generation , and this is the special culture of karst environment 喀斯特环境是形成喀斯特文化的地理背景。通过对喀斯特环境人地关系的生产和生活的研究，本文认为喀斯特文化是喀斯特地区的居民生产、生活的创造、传承及其结果表现，是喀斯特环境中特有的文化。
In light of the problems of aggravated soil erosion and litho - desertification of the karst regions in northwest guangxi as a result of degradation of forest ecosystems , six " grain - for - green " models ( five models of artificial afforestation or grass planting , and one model of desertation for natural vegetation restoration ) were screened out for quick restoration of vegetations in the regions and evaluated for their respective ecological effect 摘要针对桂西北喀斯特地区森林生态系统退化造成的水土流失加剧以及石漠化严重的现状，筛选适合该地区植被快速恢复的5种人工造林（草）方式和自然抛荒恢复模式，分析评价各种模式的生态效应。
Thirdly , the mathematics model of forecasting low flow was established in fengcong and fenglin regions according to these factors influencing the amount of low flow in karst drainage ( the area of drainage , lithology , the type of landforms and its special assembly and forest ) the conception of low water resources carrying capacity was first put forward according to the changing law of low water resources in space and the situation of exploitation and utilization in karst drainage ( ie , under the condition of the virtuous ecological environment and the available technology , the explorable amount of water resources in certain areas is capacity and limitation which is able to coordinate the development of population , enviroment and economy during the period of low flow seasons ) and preliminarily analyzed its connotation , characteristic and established the index system of low flow in karst drainage 三是根据影响喀斯特流域枯水径流的下垫面因素(空间尺度、岩性、地貌类型、植被) ，分别对峰丛和峰林等喀斯特地区建立枯水径流预测模型。根据喀斯特流域枯水资源的空间变化规律以及实际开发利用状况，首次提出了枯水资源承载力的概念，即在枯水季节期间，保持良性的生态环境和现有的技术条件下，某一区域内可开采的水资源量对支持该地区人口、经济与环境协调发展的能力和限度。并初步分析了枯水资源承载力的内涵、特性，从水资源的供需方面确立了喀斯特流域枯水资源承载力的指标体系。
The article study soil enzyme activities and the content of soil organic carbon in zanthoxylum bungeanum forest in karst area of huajiang in guizhou province , the results shows : the content of oxidizable organic carbon was increased with the increasing of plantation age in karst area , which implied karst eco - environment declined 摘要本文通过对花江喀斯特地区花椒人工林演替过程中部分土壤碳转化酶的活性以及不同活力活性有机碳研究，得出在喀斯特地区花椒人工林中随着种植年限的增加，土壤中活性有机碳的含量不断上升，生态环境处于恶化的变化过程中。
Within less than ten years " tourism development , the tourism activities have had a negative effect on the natural , cultural environment there . the vulnerability of natural and eco - culture environment determines the necessity for the village to develop minority eco - culture tourism . ( 3 ) . it evaluates the potential for development of minority eco - culture tourism in the village from three aspects : resource value , tourism environment and development conditions 通过分析得出以下结论：镇山村是黔中喀斯特地区典型的少数民族村寨，拥有丰富的自然与文化生态旅游资源;村寨在1998年被列为生态博物馆，旨在保护布依族文化，但该村发展旅游不过十年的历史，旅游活动己对其自然、文化环境造成了明显的负面影响，可见，喀斯特自然与文化生态环境的脆弱性，决定了该村发展民族文化生态旅游的必要性。
In order to accomplish sustainable economic and social development in the areas , it is necessary to start from the following four aspects : intensifying efforts to make nine - year compulsory education basically universal and basically eliminate illiteracy among young and middle - aged adults in rural areas , vigorously developing vocational and technical education , establishing a rural social security system , and preserving the natural environment 要实现西南喀斯特地区经济社会的可持续发展，需从以下四点入手：加大农村“两基”普及力度，大力发展职业技术教育，建立健全农村社会保障体系，维护良好的生态环境。
This paper studies the specific natural characters and socio - economic function in the karst area of south china and proposes a number of eco - environment protection strategies and measures for sustainable development of population , resources and environment in the karst region so as to facilitate the application to the world natural heritage 文章依据中国南方喀斯特地区独特的自然特征和社会、经济功能，借助申报自然遗产机遇，为实现该区人口、资源、环境与社会的可持续发展，提出了一系列针对中国南方喀斯特地区的保护策略及措施。
