摘要
以北京市十三陵林场为例,运用北京市"十五"森林资源二类清查数据,在完备性、可操作性、可比性和应用性原则指导下,从森林生态系统的完整性、稳定性、可持续性建立森林健康评价指标体系。使用层次分析法赋予指标权重,基于ArcGIS9.2对十三陵林场15个小班进行森林健康评价。结果表明,该林场76.69%的林分处于健康和亚健康状态,主要由人工侧柏中龄林和人工侧柏幼龄林组成。须采取切实可行的森林经营管理措施,提高经营管理水平,发挥森林更大的综合效益。
Taken Beijing Shisanling forest farm as an example,applying forest resources inventory of the tenth five-year plan in Beijing and following the guidance of the principles of completeness,maneuverability,comparability and applicability,the forest health assessment indicator system was established based on the integrality indicators,stability indicators and sustainability indicators.Applying the method of analytical hierarchy process to confirm the index weight,forest health of 15 subcompartments was assessed with ArcGIS 9.2 in Shisanling Forest Farm.The result showed that 76.69% of the stands were in good health or sub-health condition.Most of the forests were composed of middle-aged and young artificial orientalis forest.Measures of forest management should be taken to improve the level of forest management and to produce comprehensive benefits of forest.
