摘要
根据吐鲁番地区社会文化、经济、自然禀赋的具体特点,建立了人类活动强度分析评价的指标体系。利用吐鲁番地区2002—2011年的相关统计资料数据,采用变异系数法和权重加权法计算了2002—2011年吐鲁番地区人类活动强度指数。从结果来看,10年来吐鲁番地区的人类活动强度指数从0.127到0.756,10年间增长了近6倍。其中鄯善县成为全区人类活动强度最强的地区,吐鲁番市和托克逊县人类活动强度呈现出持续增强的趋势。从各指标权重和人类活动强度变化情况分析得出:影响人类活动强度的主要因子是人类各种经济活动,尤其是荒地开垦、全社会固定资产投资、产业结构调整等方面。因此,根据吐鲁番地区水资源短缺、生态环境脆弱的现状,在进行各种经济活动时,要将维护生态稳定作为经济活动的前提,降低人类活动对自然环境负面的扰动程度,以维护社会经济系统和生态系统的健康、稳定发展。
According to the specific characteristics of socio-cultural,economic and natural endowments of the Turpan Prefecture,an index system of human activity intensity quantitative analysis is established.The intensity and index of human activity in Turban Prefecture are calculated by taking advantage of relevant statistical data from 2002 to 2011,the variation coefficient method and the weighted method for the past 10 years.It can be seen from the results that nearly 10 years the human activity intensity index of Turpan Prefecture has increased nearly six-fold from0.127 to 0.756.Of which Shanshan County in the prefecture can be the strongest areas of human activity intensity,the intensity of human activities in Turpan city and Tuokexun County has shown an enhancing trend.Analysis from the index weight changes and human activities can come to the conclusion that the main factors that affecting the intensity of human activity is human economic activities,especially wasteland reclamation,fixed asset investment,industrial structure adjustment and so on.Thus,according to the situations with water shortages and fragile ecological environment in Turpan Prefecture,maintaining ecological stability must be taken as aprerequisite for economic activity in carrying out various economic activities.Reducing the degree of disturbance of human activities on the natural environment negatively and maintaining healthy and stable development of socio-economic systems and ecosystems are the most important measures that should be adopted.
