选择土壤含盐量、土层厚度、地下积水位、冲风口等4个因素对丹东岫岩区域的日本落叶松、红松在不同立地条件下的生长情况进行调查。结果表明：日本落叶松在土壤含盐量较低(0.21%)的区域造林,生长表现最好,其胸径比其他2区(含盐量分别为0.12%和0.28%)高5%~10%,树高生长量高出4.4%~19.6%；表土层厚度>10 cm,更新效果较好；日本落叶松在常年积水的立地条件下,造林成活率为58%,5 a 后保存率为43%,列为重点更新对象；在主风口立地条件下,红松造林保存率为16%,比正常立地条件下低82个百分点,12年生树高生长量为0.13 m,胸生长量为0.1 cm,均比正常立地条件下低。

Growth of Larix kaempferi &Pinus koraiensis under different site conditions was investigated by choo-sing soil salinity,soil thickness,underground water bit & tuyere in Xiuyan Region of Dandong City.Result shows that the growth of Larixkaempferi is optimal under lower soil salinity (0.21%);DBH of Larixkaempferi is 5%-10% higher than that of the other two areas (salt content being 0.12% and 0.28%,respectively);height growth of Larixkaempferi is 4.4%-19.6% higher than that of CK;the regeneration effect is optimal while the topsoil thickness > 10 cm;the afforestation survival rate of Larixkaempferi is 58% under perennially waterlogged area, and the preservation rate is 43% five years later as a key regenerated objects;preservation rate of Pinuskoraiensis is 16% under the site condition of tuyere,and is 82% lower than that in normal site condition;the growth of height &DBH of 12-year-old Larixkaempferi is 0.13 m & 0.1 cm,which are all lower than that under normal site condi-tions.
