九宫山森林生态资源自然价值量研究

本文在确定森林生态资源质量评价指标及自然环境因子价值标准的基础上,对九宫山地区森林生态资源的自然价值进行了计量研究。结果表明:1、森林生态资源价值受资源质量及资源环境的影响。资源质量越好,地形坡度越大,降雨越多,资源价值越高,反之亦然。2、九宫山森林生态资源自然价值量约为8400万元,资源年增量约为150万元,年增长率为1.8%,资源的再生产处于相对稳定状态,资源的年增长更多的是资源质量的提升。3、在不同类型中,针阔混交林的价值最高,针阔混交是该地区提高资源价值的最佳途径和模式,阔叶林在该地区的价值构成中占到接近50%的比例,但单位面积的价值不高。4、同一类型资源的价值变异比较明显,除灌木林、竹林外,针阔混交林、阔叶林、针叶林、四旁林单位面积的价值变异较大,森林生态资源的价值计量必须对计量对象进行实地、具体的调查,才能达到目的。

Study on the Natural Value of the Forest Ecological Resources in Mount Jiugong

The quality indices and the natural environmental value standard were determined in this paper,on the base the natural value of the forest ecological resources was calculated in Mount Jiugong,the main results were showed as follows.1.The value of forest ecological resources was influenced by the resources quality and theenvironment.2.The total value of the forest ecological resources in Jiugong was 84 million yuan RMB,the annual growing amount was 1.5 million yuan RMB,the growing rate was 1.8%,which was lower than average level of Hubei Province.3.Among the types of the resources,the value of mixed coniferous and broad-leaf stand was the highest,the broad-leaf forest was a proportion to 50 percent.4.The value of one type of forest ecological resources variated obviously,except the brush wood and bamboo grove.
