摘　　要：以潭江流域为例估算生态资产:(1)流域森林生态资产持续增长,但增长速度较慢;(2)按主要林种生态资产总价值排序分别为:湿地松>马尾松>阔叶林>桉树>杉树>针阔混林>相思>针混林>木麻黄>南洋楹>黎蒴,而单位面积生态价值排序为:木麻黄>相思>杉树>湿地松>针混林>阔叶树>马尾松>桉树>针阔混林>黎蒴>南洋楹,与目前造林采用的以耐酸耐贫瘠的先锋林种为主有关;(3)潭江流域生态资产空间分布存在明显差异,按县级行政区排列,台山最大,依次为恩平>开平>鹤山>江门市区;(4)潭江流域单位面积生态资产为全球热带/亚热带单位面积生态资产的44.22%,说明流域现有森林结构生态效益较差,在造林过程中过应以地带性植被为主,逐渐替代目前林种。从总体来看,潭江流域以先锋林种进行造林营林不利于流域生态效益的充分发挥。In this paper, a case study on Tanjiang river basin, difference of forest ecological capital construction and space distribution are discussed in small scale region, the finding as following： （1） The woods ecology capital and property continuees the increase,but the speed of growth is slower; （2）due to different forest species consist, the total value of different forests exist differentia, according the sequence from big to small, the result is： Pinus Elliottii〉Pinus Massoniana〉 Broad-leaved tree〉Eucalyptus〉Cryptomeria japonica D〉Coniferious and broadleaf mixed forest〉 Acacia auriculiformis〉Conifefious〉Casuarinas〉Albizzia falcata〉Castanopsis fissa, by per area ecological capital, Casuarinas〉 Acacia auriculiformis 〉 Cryptomeria japonica D 〉 Pinus Elliottii 〉 Coniferious 〉 Broad-leaved tree 〉 Pinus Massoniana 〉 Eucalyptus 〉 Coniferious and broadleaf mixed forest 〉 Castanopsis fissa 〉 Albizzia falcata; （3）the space-distribution of ecological capital principle as： Taishan＇ s〉 Enping＇ s〉Kalping＇ s〉Heshan＇ s〉Jiangmen municipal＇ s; （4）eco-capital per area in Tanjiang river basin is 44.2% of world tropic/sub-tropic forest eco-capital per area.the results indicates that present reforest methods are not benefit for improving forest eco-capital in Tanjiang fiver basin, it is necessary to ameliorate forest construction and use native tree species to increase reforest efficiency.
