Among 1 360 cases of unwanted pregnancy，21.62 % are unmarried，78.38 % are married；age distribution ranges between 20～39（73.82 %）；pregnant time distri-bution is between the second and third pregnancy（57.87 %）；44.34 % is due to contraceptive failure，55.66 % is due to no contraceptive use；IUD accounts for 10.51 % of choice of contraceptive measures，use of condoms is 10.51 %，contraceptive is 8.24 %，external use is 6.62 %， other mean is 8.46 %. The main reasons of unwanted pregnancy are due to taking chances with no contraceptive use or no contraceptive use after removal of IUD；98.90 % of interviewed subjects know contraceptive knowledge，15.37 % know emergency contraception，18.38 % know the necessity of contraception measures for nursing mothers. Married people get information of the contraception knowledge mainly from medical workers，family planning cadres，publicity materials.
