杉木人工林是通过人为高度控制新形成的人工林生态系统,其生长发育的整个过程都深受人为栽培技术措施的影响。因此,研究杉木人工林的栽培技术,对于提高杉木的产量和质量具有一定意义。定量地研究杉木人工林生态系统中的物质积累、运转、分配和能源规律,以探索决定杉木生长发育的内在生理因素和外在生态条件乃是研究杉木人工林栽培技术的先决条件,而杉木人工林生物产量和生物构造的调查研究则是这种定量研究的手段和基础。
Cunninghamia lanceolata plantation is a newly formed artificial forest ecosystem through artificial height control. The whole process of growth and development of Cunninghamia lanceolata plantation is deeply influenced by the technical measures of artificial cultivation. Therefore, the study of Cunninghamia lanceolata plantation cultivation techniques, to improve the yield and quality of Chinese fir is of some significance. It is a prerequisite to study the cultivation techniques of Cunninghamia lanceolata plantation to quantitatively study the matter accumulation, operation, distribution and energy law in Cunninghamia lanceolata plantation ecosystem in order to explore and determine the intrinsic physiological factors and external ecological conditions of Cunninghamia lanceolata plantation growth and development, Investigations of biomass production and biota in forests are the means and basis for this quantitative study.
