摘要
本研究通过全面调查、标准地实测和树干解析，调查了官司河流域主要森林树种马尾松、柏木的生长状况。建立了马尾松、柏术现实林分生长过程表，并分析了两个主要树种林分因子生长过程，评定了该流域林地平均立地质量，预测了林分发展趋势，为掌握林分动态，开展各种经营活动和科学研究提供了依据。
The growth situation of main forest tree species in Guansi RiverBasin in Mianyang was investigated with the method of general forest inventory,sampling and stem analysis. The yield tables of actual forests of masson' s Pineand cypress were constructed. The average guality of forest soil is evaluatedand the deyelopment trend of forest is estimated. The base condition and imformation of forest and its environment are provided for research and managementactivities.
