水杉(Metasequoia glyptostrobides)是江南水网地区农田林网的主要组成树种。近几年来,人们对水杉防护林网的气象效应和增产效果的研究较多,但对构成林网的林木生长、物质生产、积累和分配等问题报道很少。本文初步研究了水杉防护林带的生长量和生物产量,旨在评价水杉的生长状况、生物产量和生产力,从而较完整地评定水杉防护林网的综合效益。
Metasequoia glyptostrobides are the main tree species of farmland forest network in Jiangnan water network. In recent years, there has been much research on the meteorological effects and yield increase effects of Metasequoia glyptostroboides shelterbelts. However, there are few reports on such issues as tree growth, material production, accumulation and distribution of forest shelterbelts. In this paper, the growth and biomass of Metasequoia glyptostroboides forest belt were preliminary studied in order to evaluate the growth status, biomass yield and productivity of Metasequoia glyptostroboides and evaluate the comprehensive benefits of Metasequoia glyptostroboides shelterbelts.
