中文摘要	喀斯特石漠化地区由于特殊的地质结构以及植被破坏,导致降水很快渗漏流失,随着经济快速发展,面临着保障生产生活用水与植被生态用水的双重压力。为此,采用纵向比较与横向比较相结合的方法,并借助遥感技术手段,分析经济快速增长背景下,喀斯特石漠化典型区贵阳市的生态用水增长潜力。发现:1)贵阳市水资源相对丰富,但每年难以直接利用的地下水量占水资源总量的比例高达30.12%;2)相对于降水量的年度变化,生产生活用水量相对稳定,2008年以来每年维持在10.23亿m~3左右;3)相比生产生活用水,贵阳市生态环境用水量呈缓慢增长特征,且未来有大幅增长的趋势;4)贵阳市多年平均绿水量占降水的比例为48.71%,低于全球平均水平(65%) 16百分点,具有良好的增长潜力。
英文摘要	[Background]Due to the special geological structure and the destruction of vegetation in karst rocky desertification area,the rainfall quickly leaks and is lost.With the rapid economic development,there are the dual pressures of ensuring water for production and domestic use as well as ecological water for vegetation.Guiyang city,the capital of Guizhou province,has developed rapidly in recent years and is located in the center of karst rocky desertification in southwest China,was selected as the study area to analyze the growth potential of vegetation ecological water use.[Methods]With a combination of vertical comparison and horizontal comparison,the change trends of production water usage,domestic water usage and ecological water usage in the study area from 2003 to 2013 were compared,and the total water resources of the study area were combined to analyze the growth potential of ecological water consumption.In addition,remote sensing technology was also combined to reveal the potential growth area of vegetation ecological water usage.[Results]1) Guiyang is relatively rich in water resources,but the groundwater that was difficult to use directly accounted for up to 30.12% of local total water resources in every year.2) Relative to annual change in precipitation,the production and domestic water usage were relatively stable,and maintained at around 1.023 * 10~9 m~3 every year since 2008.3) Compared with production and domestic water usage,Guiyang's ecological water consumption showed a slow growth trend,and it would be a substantial increase in the future.4) The multi-year average green water in Guiyang city accounted for 48.71 % of the precipitation,which was 16 percentage points lower than the global average (65%),and there will be growth potential.[Conculsions]For karst rocky desertification areas with relatively abundant water resources but severe vegetation destruction,increasing ecological water usage has great potential,and it is a more feasible way to increase ecological water usage by restoring vegetation.The above analysis presents certain reference significance for the study of ecological water usage and reduction of soil erosion in similar areas.
