子午岭林区森林资源消长变化状况的探讨

Study on the Growth and Decling of Forest Resources in Ziwuling Forest Region

本文对子午岭林区油松等7个主要树种的材积生长率、生长量、及枯损量消耗量进行了调查分析。认为子午岭林区森林蓄积量出现增长趋势;今后应大力营造油松人工用材林,加强培育,适当发展山杨林;还应采取措施,降低薪材消耗量。

The volume increment percent, volume-growth, volume deteriorated and volume consumption of the seven major tree species (P.tabulaeformis etc.) in the Ziwuling forest region have been studied. The results showed that the volume-increment has ascending tendency. It is proposed that Pinus tabulaeforms should be afforested as well as Populus davidiana should be cultivated extensindy. Probable central maesure should be taken to reduc. the fuel-wood consumption.
