【摘要】 针对沿海沙地木麻黄单一树种防护林结构简单和人工林群落生态系统稳定性弱的特点，在惠安赤湖国有防护林场开展了木麻黄与台湾栾树混交造林研究，采用木麻黄与台湾栾树分别按3∶3、2∶3和1∶3比例行状混交，以木麻黄纯林与混交林对比，对9年生的试验林进行测定，结果表明：混交林中木麻黄生长量大于木麻黄纯林，树高、胸径差异不显著，平均单株材积和单位面积平均蓄积量存在显著差异和极显著差异；木麻黄+台湾栾树1∶3混交林中台湾栾树的生长量最大；木麻黄+台湾栾树混交林土壤的容重小于木麻黄纯林土壤，孔隙度大于木麻黄纯林土壤；木麻黄纯林的防风效果略好于木麻黄+台湾栾树混交林，混交林中木麻黄+台湾栾树3∶3混交林的防风效果稍好于其余2种混交林。更多还原

【Abstract】 In view of simple structure of Casuarina equisetifolia in coastal sandy land and weak stability of artificial forest ecosystem, the mixed afforestation of C. equisetifolia and Koelreuteria elegans was carried out in Huian Chihu state-owned forest farm. The row ratio of two tree species were 3:3,2:3 and 1:3 used in this trial to compare the mixed stand and pure C. equisetifolia stand. The results revealed that the growth increment of C. equisetifolia in mixed stand was bigger than that of 9-year-old pure stand, but the difference was not obvious. The growth increment of K. elegans in 1:3 mixed stand was the biggest. The soil volume-weight of mixed afforestation was lower than that of pure stand, but the porosity increment was bigger than that of pure C. equisetifolia. Windproof effect of pure C. equisetifolia stand was slightly better than that of mixed stand, among which mix proportion of 3:3 stand was slightly better than those of other two kinds of mixed stand.更多还原
