摘要:

以广东省天然林资源数据库为基础,从中选择8项天然林小班属性因子,建立天然林资源质量评价指标体系。采用模糊综合评价法,对广东省天然林资源质量水平进行评价,并进行相关性分析。结果表明,广东省内不同区域中,以粤北区域的天然林资源质量最优(2.421 4),粤东区域天然林资源质量评价分值相对较低(2.041 6)。全省各区域的天然林资源质量总体评价分值排序为粤北区域>珠三角区域>粤西区域>粤东区域。按生态区位对总体评价分值进行排序,国家级自然保护区、世界自然遗产>重要水库>江河两岸>荒漠化和水土流失严重地区>沿海基干林带。广东省天然林资源质量总体评价分值为2.381 8,各区域总体评价值均高于“中”级;影响天然林资源质量的关键因素是每公顷蓄积量、龄组和平均胸径,与综合评价结果相关性最高的2个指标分别是郁闭度(覆盖度)和龄组。

Abstract:

Based on the database of natural forest resources in Guangdong Province,eight attribute factors of natural forest sub-compartment were selected from it,and an index system for the quality evaluation of natural forest resources was established.The fuzzy comprehensive evaluation method was used to evaluate the quality level of natural forest resources in Guangdong Province,and its correlation was analyzed.The results showed that among the different regions in Guangdong Province,the quality of natural forest resources in northern Guangdong was the best (2.4214),and the evaluation score of natural forest resources in eastern Guangdong was relatively low (2.0416).The comprehensive evaluation values of natural forest resource quality in various regions of the province were ordered as follows: Northern Guangdong Region>Pearl River Delta Region>Western Guangdong Region>Eastern Guangdong Region.The comprehensive evaluation values were sorted according to ecological location: National Nature reserves/ World Natural Heritage sites>important reservoirs>banks of rivers >desertification and serious soil erosion areas>coastal shelter forest base trunk forest belt.The comprehensive evaluation values of natural forest resource quality in Guangdong Province was 2.3818,and the overall evaluation value of each region was higher than that of "medium".The key factors affecting the quality of natural forest resources were the stock volume per hectare,the age group and the mean DBH,and the two indicators with the highest correlation with the comprehensive evaluation results were the degree of closure (coverage) and the age group.
