【摘要】 在黄山高海拔景区植被残缺地段进行黄山松、黄山花楸人工种子雨修复植被试验,1.5年生黄山松幼苗平均保存株数37.6株/m2,黄山花楸幼苗12.0株/m2,两者合计49.6株/m2;黄山松幼苗平均高度6.13 cm,黄山花楸幼苗平均高度4.16 cm。结果表明:采用当地植被物种具有较高的有效种子发芽数量和保存率,体现较强的环境适应性,对景区植被残缺地段的恢复具有很大的促进作用。更多还原

【Abstract】 Vegetation restoration experiments were carried with artificial seed-rain sowing of Pinus taiwanensis and Sorbus amabilis in vegetation-lacked sections of the high-altitude scenic region in the Yellow Mountains. The mean number of the surviving 1.5-year-old seedlings of Pinus taiwanensis was 37.6 /m2,and that of Sorbus amabilis was 12/m2,totaling 49.6/m2together. The mean height of the Pinus taiwanensis seedlings was 6.13 cm and that of the Sorbus amabilis seedlings was4.16cm. The results showed that the indigenous vegetation species had higher effective seed germination rates and survival rates, displaying better environmental adaptabilities,and these species could greatly promote the vegetation restoration in vegetation-lacked sections of the scenic region.更多还原
