九龙江流域森林生态修复模式建立与评价

Jiulong River Forest Ecological Restoration Modeling and Evaluation of

通过对九龙江上游流域森林生态环境现状调查分析，表明：九龙江上游流域森林生态系统仍然脆弱，森林结构不舍理，林种、树种、龄级结构比例失调；林分总体质量下降，并严重导致为空间分布不均衡的破碎性和单一性的残次林；森林资源管护机制不落实，环境污染和“青山挂白”急待绿化整治。按照“绿、亮、美”要求和以人为本的原则，建立了适宜九龙江上游流域森林生态修复模式，并对实施效果进行评价。

Jiulong River watershed upstream status of forest ecological environment investigation and analysis showed that： Jiulong River watershed upstream is still fragile forest ecosystems, forest structure is irrational, forest types, tree species, age class structure of proportion; forest decline in the overall quality, and Serious led to the uneven spatial distribution of fragmentation and unity of the defective forest; forest resources management mechanism is not implemented, environmental pollution and the ＂Green Mountains white＂ urgent need of green remediation. In accordance with ＂green, bright, beautiful＂ people -oriented requirements and the principle of establishing a suitable Jiulong River watershed upstream of forest ecological restoration model, and the results are evaluated.
