摘　　要：对全省18个县24块新营建的降香黄檀林分在2011∽2013年连续开展寒害和生长调查，分析结果表明：降香黄檀林分早期生长较快，树高年均生长可达1.05 m，胸径年均生长达1.03 cm，但是个体间差异较大；当最低温在0∽5℃之间并保持5∽10天时，降香黄檀出现较为严重的寒害，林分寒害等级与月均温、海拔、树高和林龄呈极显著的负相关，与纬度、胸（地）径呈极显著的正相关；林分所处地形对寒害等级也有一定影响；受寒害的林分在次年寒害较轻的情况下可恢复生长。依据各地寒害等级，并结合各地气温及寒害恢复情况，绘制广东省降香黄檀人工林寒害分区图，将全省划分为适宜栽培区、次适宜栽培区、风险栽培区和不适栽培区四种类型。Twenty-four plots of Dalbergia odorifera plantation in 18 counties across Guangdong province were selected for the successive investigations of growth and chilling injury of tree species from 2011 to 2013. The results show that D. odorifera displayed a quick early growth with an annual increase of 1.05 m in tree height and of 1.03 cm in diameter at breast height;there were significant differences among individuals in the tree growth and chilling injury;the species suffered severe continuous chilling injury for 5∽10 days with minimum air temperature 0∽5 oC;the injury degree was negatively correlated with monthly mean air temperature, altitude, tree height and age, and positively with latitude and diameter;the geography was also found to have impacts on the injury degree of D. odorifera;the injured individuals had the potential to recover in the next year with less chilling climate. Based on the injury degree, temperature variation and recovery situation, the zoning map of chilling injury for D. odorifera plantations was drawn out, in which the whole Guangdong province was divided into four cultivation areas：suitable, sub-suitable, risky, and unsuitable cultivation area.
