摘要
根据云南省已有的松脂资源数据,对各州、市的采脂松树资源和松脂贮量进行了对比分析。通过松脂年产量、产脂树种及分布、产脂松林和其中的用材林资源总量及松脂贮量的对比分析,归结出了云南省各州、市松脂资源的现况及特点。比较分析结果表明:云南省各州、市的松脂资源数量和质量差别巨大。普洱市的年松脂贮量为全省最大,大理州产脂松林及其后续资源中幼林的面积为全省最多,从而形成了以云南省的澜沧江中下游流域为中心的松脂资源和松香生产聚集核心地带。
Applying pre-existing data,the resin resource storage of different areas in Yunnan province were compared and analyzed.Several parameters such as annual resin yield,pine tree species and distribution,resin production stand,timber forest resource and resin storage,were considered.Based on the analysis,the current status and characteristics of resin resources in different prefectures and cities of Yunnan province were summarized.The research results showed that both amount and quality of resin from different areas varied significantly.Pu＇er is the city with the biggest annual production,Dali prefecture owns the richest potential resource.It is concluded that the middle and lower reach of lancing river watershed is the core zone of resin resource storage and rosin production.
