摘要: 根据大量的样地材料,从宏观上阐明了杉木林生物生产力的地理分布格局和水热相关规律,建立的生产力地理分布模型客观地反映了杉木高产林区的地理分布规律。根据限制因子作用律建立了杉木林生物生产力水热优化模型,模型显示杉木林生长最适宜的水热组合环境为:年均气温16~17℃,年降水量1700~1900mm,温暖指数145—150℃月,潜在蒸散量920~930mm,这时杉木林乔木层的生产力达17~18t·hm-2·a-1,全林生产力达21~22t·hm-2·a-1。
Abstract: According to a lot of plot data, the productivity distribution patterns of Chinese-fir plantations related to geographical or hydro-thermal factors were clearly indicated. The geographical distribution model established here objectively reflects the geographical patterns of the high-yield Chinese-fir plantations. In terms of the ecological limitation rule, the optimal models of Chinese-fir productivity vs. hydro-thermal factors were set up, showing that the hydro-thermal factors ,which are most suitable for Chinese-fir growth ,are as follows: annual mean air-temperature 16~17 ℃ , annual precipitation 1700~1900 mm, warm index 145~150 ℃ month, Thornwaite’s potential evapotranspiration 920~930 mm. Under the climate conditions, the productivity of Chinese-fir plantations can be up to 17~18 t·hm-2·a-1 for arbor layer and 21~22 t·hm-2·a-1 for the whole forest.
