摘要
以蛮汉山油松人工林为研究对象,在科学性、代表性、可操作性、系统性原则的指导下,以野外实地调查为基础,采用定性与定量结合法、频数分析法、等距划分法、均方差综合分析法提出一套评价内蒙古中部山地油松人工林健康状况的指标体系;运用模糊综合评价法对内蒙古中部油松人工林进行评价,结果表明:研究对象多数处于亚健康状态,须采取抚育措施,向健康方向调整,发挥其更大的综合效益。
Taking Pinus tabulaeformis plantation of Manhan mountain as the research object, under the guidance of the principles of scientific attribute, representativeness, easy maneuverability, system integrity and based on field investigation, Pinus tabulaeformis Plantation health assessment indicator system in central Inner Mongolia was established which was based on the combination of qualitative analysis and quantitative analysis, Frequency analysis method, Isometric Cut method and Mean - variance comprehensive analysis method. Results showed that most of these forests in Manhan mountain are in sub - healthy condition. Intermediate thinning measures must be taken to adjust the stand to the healthy development, and to produce a better comprehensive benefit of Pinus tabulaeformis plantation.
