中文摘要	人口是可持续发展的关键，人口数量、人口质量、人口结构等各种人口因素在内的人口变动对干旱区生态环境具有直接的制约和影响。本研究采用理论研究与实证研究想结合、定性分析和定量分析相结合的研究方法，在分析干旱区生态环境演化的规律基础上，建立了塔河流域土地荒漠化中人类因素的评价指标体系，分析人类因素在土地荒漠中所占的贡献率，进一步从塔河流域的人口规模、人口空间分布、人口素质、人口结构等各种人口因素在内的人口变动对干旱区生态环境的关系做了分析。从而对塔河流域生态环境安全提出相应的人口战略。本文主要为五个部分，其中第三、第四是重点内容。第一部分：阐明本文的选题背景。研究意义、研究方法和试图取得的创新点，综述了国内外人口与环境相关的研究成果，简介人口与环境研究的几种方法。第二部分：阐述干旱区生态环境演变的过程和演变阶段，分析了塔里木河流域生态环境基本态势及其近期变化特点，综合分析了塔河流域生态脆弱性。第三部分：在塔河流域土地荒漠化的影响因素的分析基础上，构建人类因素对土地荒漠化影响的贡献率的评价指标体系，同时介绍了定量分析的方法。第四部分：分析了人口变动对生态环境的影响机制，进一步从人口的人口空间分布、人口素质、人口结构等各种人口因素在内的人口变动对干旱区生态环境的关系做了分析，并对其对生态环境的未来影响趋势做了分析。第五部分：提出塔河流域生态安全的人口战略选择：（1）建立以水为中心的绿洲PRED优化体系；（2）强化生态环境安全的法制观念，培育生态环境安全的人文环境；（3）实行计划生育政策，限制人口增长，提高人口素质；（4）合理引导人口的迁移，制定切实可行的人口迁移政策；（5）通过转变经济增长方式、产业升级进行人口调控。第六部分：简要列出初步研究的结论，为进一步深入研究提出了设想。Population is a key factor to sustainable development, and every part of which influences on ecological environment directly in the arid area，such as population quantity, quality, structure and so on .This paper based on academic demonstration and qualitative analysis. After analysis of ecological environment evolution in arid area，a population indicator system of the land desertification is framed and the contributions of each indicator are accounted .And then，the relations between population quantity, quality, and structure are analyzed .At last, some suggestions on population development are put forward to sustain ecological environment security. This paper contains six parts totally，in which part 3，part 4 are the most important parts. In part one：The reasons to do this research，research approach，research route and innovations this paper trying to obtain are clarified. Domestic and international research results relevant are summarized. In part two： Ecological environment evolution process and evolution stages of he arid area are expounded. The basic situation of ecological environment and the change characteristic of the Tarim River basin are analyzed，and the ecology vulnerability of Tarim River basin is generalized. In part three：Based on analysis of influential factor on land desertification in Tarim River basin， the indicator system is set up to solve how human factors contribute to the land desertification, and meanwhile, quantitative analysis method is introduced. In part four：On the basis of analysis on the interacting mechanics between population change and environmental evolution， relations between changes of population and ecological environment in arid land are discussed, which includes population’s factors, such as the spatial distribution, the quantity, the quality, the structure of population. Furthermore, the tendency that population factors affect ecological environment is predicted. In part five：According to the above analysis，strategies of Ecological environment security are arisen.(1) Establishing oasis PRED optimization system which take water as central ;(2) Strengthening ecological environment security concept of law and cultivating humanities environment of ecological environment security ;(3) Putting family planning in practice insistently，limiting the population increase and enhancing population diathesis;(4) Making the practical and feasible population migration policy and guiding population migration; (5) Coordinating the population regulation through the transformation of economy growth way and the industrial promotion. In part six：In the conclusion and discussion，some conclusions in recent phase are presented and some ideas are brought to make the paper better in future.
