摘要
本文以福建省平潭岛四种主要沿海防护林为研究对象,通过区域标准样地调查与室内实验相结合,对防护林树种主要生态效益进行观测。以层次分析法为指导,建立综合生态效益评价体系,系统地评价平潭岛沿海防护林生态效益。以评价体系为依托,运用“边际效益”理论对平潭岛生态效益最大化进行模拟。研究主要结论如下:(1)平潭岛沿海防护林林下土壤呈酸性,肥力缺乏,土壤普遍贫瘠;生物量:湿地松林(312.16t/hm2)>木麻黄林(189.82t/hm2)>黑松林(146.28t/hm2)>台湾相思林(87.71t/hm2);防护林对温度、湿度、风速均有较大的调节作用,其中对风速调节最为明显。(2)凋落物持水量随着浸水时间增加而增大,吸水速率则随着浸泡时间增加而递减。凋落物持水量:台湾相思林>木麻黄林>黑松林>湿地松林;林分土壤蓄水量:黑松林>台湾相思林>木麻黄林>湿地松林。(3)防护林土壤碳含量和碳储量均随土层深度增加而减少;树种平均碳含量:黑松林(49.2%)>湿地松林(49.07%)>台湾相思林(48.59%)>木麻黄林(45.55%);固碳释氧量排序:湿地松林>木麻黄林>黑松林>台湾相思林。(4)建立了包含四项准则层,十项指标层的平潭岛沿海防护林综合生态效益评价体系。以评价模型为基础,四种防护林综合生态效益排序为:木麻黄林(1.1623》湿地松林(1.0758)>黑松林(1.0059)>台湾相思林(0.7619)。(5)运用“边际效益”理论,模拟最大生态效益下各树种面积,结果为:木麻黄林(31.03%)、台湾相思林(17.27%)、湿地松林(51.69%),若以此面积配比种植防护林,生态效益将高出现有生态效益13.78%。
