不同恢复途径对黑龙江省森林湿地生产力影响分析

采用样带网络进行网络调查方法以及标准木解析法，并且对黑龙江天然森林沼泽群落的树种组成结构、径级分布、树木生长过程、蓄积生产力、生物量生产力以及沿过度带环境梯度的变化规律进行深入的研究，并且对人工造林途径和自然演替途径的恢复效果进行定量和评价，对退化森林沼泽群落的有效恢复途径进行探讨，为退化森林湿地生态系统的恢复与重建提供了科学的依据。

Sample with network is adopted to improve the Internet investigation method and standard analytical method,and the structure of heilongjiang province natural forest swamp community species composition,diameter class distribution,tree growth process,the accumulation of productivity,biomass productivity and excessive belt along the environmental gradient of in-depth study,and the way of artificial afforestation and natural succession way quantitatively and the recovery effect of evaluation,the approach to restore the degraded forest swamp community effectively carries on the discussion,for the degradation of forest restoration and reconstruction of wetland ecosystem provides a scientific basis
