川中丘陵区人工柏木林健康评价

Health Assessment of Artificial Cypress funebris Forests in Hilly Areas of Central Sichuan

  • 摘要: 以实地调查为基础,应用SPSS l8.0数学统计软件,采用定性与定量相结合的方法确定人工柏木林健康评价指标体系,包括结构性指标、功能性指标、适应性和环境指标4大类15个指标,分别使用主成份分析法和层次分析法赋予指标权重,对川中丘陵区126个野外样地进行森林健康评价。结果表明,两种方法的评价结果基本类似,均是亚健康和不健康的林分占绝大多数(分别为71.43%和61.90%);健康等级为优质的林分数量很少,两种方法评价结果分别为6个和9个,占4.76%和7.14%。需对川中丘陵区大多数人工柏木林分采取切实可行的森林经营管理措施,提高经营管理水平,以发挥该区域人工柏木林更大的生态、经济和社会综合效益。

     

    Abstract: In this paper,on the basis of field investigation,and by using SPSS 18.0 mathematical statistics software,and adopting the combination of qualitative and quantitative method,the artificial Cypress funebris health evaluation index system was determined,including 4 categories such as structural,functional,adaptab environmental indicators and tolalling indicators.In the meantime,using principal component analysis method and analytic hierarchy process (ahp) with index weights,the forest health assessment was conducted on 126 wild samples in the upper hillside area.Results showed that the evaluation results of two methods were basially similar;the healthy and unhealthy stands occupied the vast majority (71.43% and 61.90%,respectively); the high quality stand was few in number,and the evaluation results of two methods were 6 and 9,respectively,occupying 4.76% and 7.14%.For upper hilly-gully regions' most artificial cedar forest,feasible forest management measures should be implemented to improve the level of management in order to get more ecological,economic and social comprehensive benefits of artificial Cypress funebris.
