摘要: |
在东莞燕岭湿地公园选择 6 种植物群落,调查其植物组成、枯落物层以及土壤层的持水特性。
结果表明:样地植物共有 72 种,隶属于 45 科 64 属;6 种植物群落的乔灌草各层基本上均由 3 种植物组
成;落羽杉 Taxodium distichum 群落种植密度最大;各样地枯落物的蓄积量无显著差异,银合欢 Leucaena
leucocephala 群落和黄槐决明 Cassia surattensis+ 红花羊蹄甲 Bauhinia blakeana 群落枯落物对降水的拦蓄
能力最好。黄槐决明 + 木棉 Bombax ceiba 群落的土壤容重最大;黄槐决明 + 红花羊蹄甲和黄槐决明 + 木
棉群落的土壤贮水能力较强;水黄皮 Pongamia pinnata 群落土壤吸收、贮存降水的能力较强;黄槐决明 +
木棉群落涵养水源效果较好。 |

Abstract: |
Six plant communities were selected in Dongguan Yanling Wetland Park to investigate their plant
composition, litter layer, and water-holding characteristics of the soil layer. The results showed that there were
72 species of plants in the sample plot, belonging to 45 families and 64 genera; Each layer of arbor, shrub, and
grass of 6 plant communities is composed of 3 plants. Taxodium distichum community has the highest planting
density. There is no signi?cant difference in the amount of litter accumulation among different sites. Leucaena
leucocephala community and the Cassia surattensis+Bauhinia blakeana community have the best ability to
retain precipitation. The soil bulk density of Cassia surattensis+Bombax ceiba community is the largest; The
soil water storage capacity of Cassia surattensis+Bombax ceiba community and Cassia surattensis+Bauhinia
blakeana community is strong; The soil of Pongamia pinnata community has a strong ability to absorb and store
precipitation; Cassia surattensis+Bombax ceiba community has good water conservation effect. |
