| 摘 要： | 对于干旱区内陆河流域来说,地下水埋深是指示当地生态变化的至关重要的因子。本文以新疆塔里木河下游为例,基于少量的监测井监测数据,尝试利用分类分段横向和纵向联合回归分析方法模拟地下水位空间分布变化,以1:1万DEM为基础数据运用GIS技术实现数字地下水埋深空间化。结合生态监测井实时监测数据以及地下水分布与植被的响应关系进行模拟精度分析,表明该模拟方法在地下水位监测数据较少和水文地质条件相对单一的干旱区内陆河具有一定的可行性。

| Abstract: | The change of groundwater table is the most important factor for indicating the ecological change in continental river basin in arid land.Taking the lower reaches of Tarim River as an example,with the few data of monitoring wells,this research attempted to utilize united regression estimate analysis of classification and segmentation from horizontal and vertical aspects to simulate the distribution of groundwater.Based on the 1∶10 000 map database of DEM the spatialization of digital groundwater depth was realized by use of GIS technique.In the end,accuracy analysis was proceeded by real-time data of ecological monitoring wells and the relation between groundwater and natural vegetation,and so the conclusion was that the method has great feasibility in arid inland river area in the case that there is less monitoring data of groundwater level and the hydrogeological condition is comparatively single. |
