An experiment was conducted to study the water conservation capabilities ofPinusmassoniana and Gordonia Svchuanensvs mixed forest(MDH),Gordonia Svchuanensvs and Symplocos setchuensis mixed fort est(DSH)，Pinusmassoniana and Lindera kwangtungensis mixed forest(MKZH),Lindera kwangtungensis and Cunninghamia lanceolata mixed forest(G SZH)，Pinus massoniana burned area(MJD),and lostachyspubescens mixed forest(NMH) in Jinyun Mountains,Chongqing City. Results showed that for wagter holding capacity above ground, the order of forest types was DSH(73. 871 t/ hm²)>NMH(71.136 t/hm²)>MDH(58.103t/ hm²) >MKZH(57. 43 0 t/ hm²)>GSZH(30. 677t/hm²)>MJD(19.010 t/hm²);by the actual effect of storing of litter, NMH>DSH> MKZH> GSZH>M DH>MJD; by water-holding cat parity of noncapillary porosity, NMH(204. 300 mm)>MJD(168. 909 mm)>MKZH(145.598 mm)>GSZH(137. 547mm)> MDH (48. 919 mm)>DSH(43. 096 mm);and for water conservation capacity of different forest types, NMH(211. 4 mm)> MJD(170. 8 mm)>M KZH(151. 2 mm)>G SZH(140. 6 mm)>MDH(54. 6 mm)>DSH(50. 2 mm).
