摘要

通过实地调查与实验分析，对重庆市缙云山中马尾松+四川大头茶混交林(MDH)、四川大头茶+山矾混交林(DSH)、马尾松+广东山胡椒混交林(MKZH)、广东山胡椒+杉木混交林(GSZH)、马尾松火烧迹地(MJD)和楠竹+山矾+马尾松混交林(NMH)水源涵养的能力进行了分析。结果表明，6种林分的地上部分持水总量DSH(73.871t/hm

)>NMH(71.136t/hm

)>MDH(58.103t/hm

)>MKZH(57.430t/hm

)>GSZH(30.677t/hm

)>MJD(19.010t/hm

);各种林分的枯落物实际拦蓄效应排序为NMH>DSH>MKZH>GSZH>MDH>MJD;非毛管持水量顺序为:NMH(204.300mm)>MJD(168.909mm)>MKZH(145.598mm)>GSZH(137.547mm)>MDH(48.919mm)>DSH(43.096mm);各林分涵养水源能力顺序为NMH(211.4mm)>MJD(170.8mm)>MKZH(151.2mm)>GSZH(140.6mm)>MDH(54.6mm)>DSH(50.2mm);各林分涵养水源能力排序为NMH(0.864)>MKZH(0.767)>DSH(0.744)>MDH(0.613)>GSZH(0.512)>MJD(0.477)。

Abstract

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).
