摘要
从生态学和生态经济学的角度,在全面调查和多年定位研究的基础上,以生物生产力和木材产量为指标,论述了桂西北田林老山中山杉木引种栽培区林分生长和产量与气候、土壤、微生物、地质地貌和经营措施之间的关系,并对林分的经济效益、生态效益和社会效益作了全面分析。结果表明:田林老山中山的自然生态条件完全满足杉木速生丰产的需要,现实林分生产力与杉木中心产区相当,并大大高于扩大栽培区,达到速生丰产林的标准。获得了显著的经济、生态和社会效益,可作为广西杉木商品性生产新基地。
<Abstract >From the points of ecology and ecological economy, based on stationary observations in many years and a complete investigation, the relations between the growth and yield of Chinese fir and the ecological factors(climate, soil, microbes, geology and topography as well as management etc. ) in the introduction area, Laoshan Mountain in Tianlin, the Northwest of Guangxi were studied by using the biological productivity and timber production as indices. The economic, social and ecological effects of Chinese fir plantation were also analysed. The results showed that the ecological conditions could meet the need of fast growth and high production of Chinese fir. The present stand productivity is as high as those in Hutong and Longsheng, the central growing areas of Chinese fir, and higher than those in other border areas in China. The increment of stand has attained the standards of fast growing and high producing forest. The economic and social as well as ecological effects of the plantation are very good, indicating that Laoshan Mountain can be used as a new base for Chinese fir commercial timber production.
