In order to understand the effect of purifying technology on the lake water in Hainan golf course,the project built three ecological ponds of A,B and C. The bottom of pond A was covered with some basaltic rocks and a kind of emergent landscape plants-thalia dealbata,the bottom of pond B was covered with some basaltic rocks,and pond C acted as a reference. We poured the lake water of Dongshan golf course into the ecological ponds and tested the quality changes of water.The results showed that 15 d is more effective than 8 d when the basal is used to purify Cr,Cu,Zn,As. The combination of basal and Thalia dealbata was more effective than single basal in purifing Cr,Cu,Zn,Hg. The purification rate of total phosphorus,CODcr and BOD_5 were 78%,56%,71% respectively,and the purification rate of Hg was 100% when the combination of basal and Thalia dealbata was used.
