摘　　要：文章以丽江黑龙潭为例,研究岩溶地区泉水修复补水控制过程。基于九子海洼地为黑龙潭泉群主要补给来源这一基本判断,从宏观的地形地貌、地层岩性、地质构造、岩溶现象和地下水位动态变化规律入手,首先明确拟采用作为补水控制信号的水文观测井与目标泉群属于同一地下水系统,而后分析观测井地下水位变化规律与目标泉群流量变化规律具有良好的相关性,可作为补水控制井。通过泉群目标状态的拟定−对应补水控制井水位−考虑补水过程提前量时间−修正补水控制井水位这一过程,确定考虑补水时间过程的补水控制井信号水位为2409.41 m,最终实现对观测井水位数据为控制信号的补水过程的实时精准控制。The paper takes Heilongtan in Lijiang as an example to study the recharge control process of spring water restoration in the karst area.Despite much work on Heilongtan in the previous period,there still exist problems in terms of the spring water restoration of Heilongtan,such as difficulties of detecting recharge sources and of controlling the recharge time,and the high cost of constructing recharge channels.On the basis of the groundwater system theory,and the spatial geographic information and geologic information of Heilongtan spring system,this paper aims to study the restoration of Heilongtan spring group,which may provide a scientific basis for the restoration of karst springs and environmental protection.The Lijiang area,where the study area is located,belongs to the low-latitude plateau monsoon climate zone,with unique mountain monsoon climate characteristics,distinct dry and wet seasons,and significant vertical climate changes,but slight seasonal variations in temperature.Because the Lijiang area is surrounded by the Jinsha River in the west,north and east,deep-cut canyons and a peninsula-like mountainous area protruding northward have been developed.With an elevation of about 2,400 m,a width of 4-5 km from east to west and a length of 32 km from north to south,the Lijiang Basin−a long and narrow mountainous basin−is located in the southern part of the Lijiang Peninsula.The study area is located in the northeast side of the mountainous area of Lijiang Basin,and the Heilongtan spring group is located in the southwest corner of the study area at the foot of Xiangshan hill in the north of the Lijiang ancient city at the east of Lijiang Basin.The study area generally belongs to the alpine mountainous terrain in the dissolution fault block,and the karst in this area is developed.Based on three-dimensional data on basic geological conditions,karst hydrogeological conditions,and characteristics of water balance,seepage field,temperature field,chemical field,etc.,connection tests have been conducted to veri
