我们应云南现代林业资源产业化课题组的邀请，于今年２月到思茅地区就开发思茅林区以及发展思茅松等速生树种的问题作过历时１５天的考察。通过考察，我们深感思茅地区自然条件优越，森林覆盖率高，发展林业潜力巨大。同时，我们也发现思茅地区的主要树种──思茅松的生产率低 At the invitation of the Yunnan Modern Forestry Resources Industrialization Task Force, we visited Simao Prefecture in February this year for a 15-day study on issues such as the development of the Simao forestry area and the development of fast-growing species of Simao pine.
