采用宏观区划和微观量化分级相结合的方法,利用气候、植被和立地区划数据,首次在全国大区域尺度上实现森林生产力三级区划,同时,结合多期森林资源清查地面样地数据实现森林生产力量化分级。以辽宁森林生产力区划和量化分级成果为案例,详细介绍本研究的技术路线和方法。该研究可为林业区划、森林生态系统功能评价等研究和实践提供理论和方法依据。

By combining macro zoning and micro quantitative classification method,for the first time,this paper realizes 3-level macroscopic division of forest productivity on national large scale based on the climate,vegetation and site classification.It realizes quantitative grading for forest productivity by using multiphase ground survey data.With Liaoning province forest productivity research results as a case,this paper introduces the technical route and method of research.The results can be used for forestry regionalization,forest ecosystem function evaluation and many other research and practice fields.
