日本岩垂草在岩溶山地的生态效益研究
Study on the ecological benefit of Lippia nodiflora (L.)Greene in karst mountain
摘要
Abstract
A high quality Japanese species - Lippia nodiflora (L. ) Greene is introduced for the first time to be planted for eco-rehabilitation in karst mountain in the paper. The ecological benefit is discussed in the paper through studying the coverage, root system characteristics, runoff and erosion resistance, whereby seeking eco-rehabilitation ways for fragile ecosystem and providing scientific basis for planting and popularizing Lippia nodiflora (L.)Greene in karst mountain. The experiments show that the amount of runoff will drop after planting Lippia nodiflora (L. )Greene, and the amount of surface runoff reduces by 62 % from 110 mm to 42 mm 3 months later. Under same rainfall intensity and capacity, the erosion amount in Lippia nodiflo-raiL. )Greene land counts to only 5. 60 % - 5. 83 % of that in traditional farming lands, and that the root system grows faster, gets denser and more. After planting 90 days, the Lippia nodiflora (L.)Greene has covered 100% of the ground surface. The experiments prove that Lippia nodiflora (L. )Greene is good for eco-rehabilitation and can improve efficiently the ecosystem and landscape in karst mountain.关键词
