摘要:
以连云港市赣榆丘陵山区植被退化的太平山为依托,开展植被退化机制生态修复技术研究,采取封禁修复措施,构建黑松—元宝枫群落、黑松—榉树群落、黑松—黄栌群落、黑松单一群落4种群落结构。结果表明,封禁修复前3年,阳坡一些地带性多年生植物种逐渐增加,并占据优势,封禁修复第4年,乔、灌、草发生了新的变化,乔灌木及藤本品种随着人工补植树种的成林反而也减少了,乔木树种减少到5科6种,灌木减少到6科9种,藤本减少到3种,无论从数量还是生长量都呈减少的趋势,植被覆盖率由93.5%下降到92.4%。取得了采用营养钵育苗,在主汛期7月份造林,平均成活率达到96.2%,保存率达85.2%的技术经验; 项目区的林草植被平均覆盖率为93.1%,群落结构呈正向演替。
Abstract:
Based on vegetation degradation of Taiping Mountain in Ganyu hilly and mountainous areas of Lianyungang City, ecological restoration technology of vegetation degradation mechanism was studied, and four community structures of Pinus thunbergii-Acer truncatum community, Pinus thunbergii-Zelkova schneideriana community, Pinus thunbergii-Cotinus coggygria community and Pinus thunbergii single community were constructed by blocking restoration measures. The results showed that some zonal perennial plant species increased gradually and occupied the dominant position in the first three years of the closure restoration. In the fourth year of the closure restoration, new changes had taken place in arbor, shrub and grass. With the forestation of artificial supplementary tree species, arbor, shrub and vine varieties decreased. Arbor species decreased to 5 families and 6 species, shrubs decreased to 6 families and 9 species, and vines decreased to 3 species. Both quantity and growth showed a decreasing trend, and vegetation coverage decreased from 93.5% to 92.4%. The technical experience of cultivating seedlings with nutritive bowl and afforestation in July during main flood season was obtained, the average survival rate reached 96.2% and the preservation rate reached 85.2%. The average coverage rate of forest and grass vegetation in the project area was 93.1%, and the community structure showed positive succession.
