在干旱区山地—荒漠—绿洲三大系统中,绿洲处于中心地位。但是随着人口的增加、社会经济的发展,绿洲生态系统所承载的压力日益增加,生态危机及可持续发展问题十分突出。确定绿洲发展的适度规模和扩张指标体系及规模预警是现代绿洲研究的核心。通过全面剖析且末绿洲系统、深入分析野外调查数据并与空间数据相结合、广泛查阅资料并分析,对绿洲规模扩张预警指标体系进行分类归并,构建了层次分明、逻辑清晰的绿洲规模扩张的预警指标框架体系,构思出3大类28项绿洲规模扩张预警指标体系,其对保持绿洲社会经济的持续、健康发展具有十分重要的战略意义。图4,参20。
In the arid area of mountain - desert - oasis three systems, the oasis at the center. However, with population growth, social and economic development, the pressure exerted by the oasis ecosystem is increasing day by day. The problems of ecological crisis and sustainable development are prominent. It is the core of modern oasis research to determine the appropriate scale of oasis development, index system of expansion and early warning of scale. Through a comprehensive analysis of Qiemo Oasis system, the field survey data are further analyzed and combined with spatial data, extensive access to data and analysis, classification and consolidation of oasis scale expansion warning index system, to build a clear, clear logic oasis scale expansion warning Indicator framework system, conceived 28 major indicators of the oasis scale expansion early warning system in three major categories, which is of great strategic significance for maintaining the sustained and healthy development of oasis socio-economy.
