新疆平原区地下水资源评价及其结果分析

Evaluation and Results Analysis of Groundwater Resources in Plain Xinjiang Area

集成3S对地球科学信息的处理与分析功能,结合VBA编程技术实现了新疆地下水资源评价计算方法的程序化和计算步骤的自动化。该评价模式为类似的地下水资源评价提供了参考,可推广应用于针对新疆某个流域或西北干旱区的地下水资源评价。新疆地下水资源评价主要结果为,总计算面积120.82×104km2,其中平原区计算面积50.91×104km2。平原区地下水多年平均总补给量337.6×108m3,总排泄量340.5×108m3。平原灌区现状开采地下水量56.4×108m3,近期和中期评价地下水可开采量约153.2×108m3。

Integrating the function of the geosciences information processing and analyzing of 3S（GPS, RS and GIS） and the programming technique of VBA（Visual Basic for Applications）, it realized proceduralization of calculation method and automatization of calculation procedure. Because the work platform is Excel progamme, the software system is apt to operate and export report forms of evaluation results. The mode of this evaluation provides us with a good reference example of similar groundwater resources evaluvation. And, it can be popularized in any basin of xinjiang or arid area of northwest. The main elevation results are as follows： Total calculated area of groundwater resources in Xinjiang is 120.82 × 10^4 km^2, including 50.91× 10^4 km^2 of plain area. The long-term average groundwater recharge in the plain area is 337.6 × 10^8 m^3 , the discharge is 340.5× 10^8 m^3. The volume of groundwater mining in the plain irrigated areas in Xinjiang is 56.4 × 10^8 m^3 in current. The potential yield of groundwater in the plain irrigated areas in Xinjiang is 153.2 ×10^8 m^3 in the short and medium terms.
