摘　　要：通常G IS技术应用到野外水文地质调查工作时需要花费大量时间准备数据,导致其不能及时参与到野外工作中。为了使G IS技术及时在1∶5万岩溶水文地质综合调查野外工作中发挥作用,笔者以湖南新田河调查为例,在M apG IS系统中根据原始资料复杂程度的不同对数据进行处理和配准,及时制作了信息丰富的野外工作用图,建立了工作区专业数据和数据录入、分析平台,在野外调查工作开展时及时录入数据并加以分析,及时修订地质边界,检查野外定点准确度,发现调查区遗漏点,优化取样点及线路等,提高了工作效益和准确度。Application of GIS techniques to karst hydro-geologic field survey usually spends a lot of time preparing digital data, which make GIS system can not be used in the fieldwork in time. In order to apply the GIS technique betimes on the fieldwork in the 1 ： 50 000 composite hydro-geologic field survey,the author edited and adjusted the digital data collected from Xintian basin by different methods based on the complexity of the data, and provided the fieldwork map that contained rich information in time, built the data platform for editing and analyzing in working area, input and analyze the data in time during the survey, edit the geologic borderline, check the position of the points recorded in field, find the miss information, optimize sampling route. All of the above has improved the data precision and work efficiency.
