针对半干旱地区华北落叶松人工林传统密度控制理论的弊端,以32年生华北落叶松人工林为研究对象,通过对土壤水分和养分的测定结果,结合华北落叶松人工林多年的生长表现,提出根据水分和养分环境容量来确定人工林合理密度的新方法,为半干旱地区华北落叶松人工林的可持续经营提供科学依据。
Aiming at the disadvantages of traditional density control theory of Larix principis-rupprechtii plantation in semi-arid area, taking the 32-year-old Larix principis-rupprechtii plantation as research object, this paper puts forward the measurement results of soil moisture and nutrients and the multi-year growth performance of Larix principis- According to the moisture and nutrient environment capacity to determine the rational method of plantation density for the semi-arid area of Larix principis-rupprechtii can provide a scientific basis for sustainable management.
