【摘要】：2016年5月中旬在江西赣南塘背小流域选取3种典型水保措施治理下的林地,通过对其乔灌草物种组成调查、生物多样性指数计算和统计分析,研究塘背小流域各代表性林地在治理30 a后的植物恢复状况。结果表明:3种水保措施条件下植被覆盖度均有变化,不同之处在于相对于仅采用"封禁"措施的林地,采用"工程+植物+封禁"措施的林地植物群落发展较快、种类较为丰富。表明仅采用封禁措施的植被恢复无显著变化,采用植物或工程措施都能够加速植被恢复,同时采用水平竹节沟和乔、灌、草相结合种植的水保措施能最大化加速水土流失区的植被恢复。
[Abstract]:In the middle of May 2016, three types of forestland under the management of soil and water conservation measures were selected from Tangbei small watershed in Jiangxi province. The species composition of Arbor, shrub and grass was investigated, and the biodiversity index was calculated and analyzed statistically. The plant restoration of representative woodland in Tangbei small watershed after 30 years treatment was studied. The results showed that the vegetation coverage varied under the three soil and water conservation measures. The difference was that compared with the forestland with only the "ban" measure, the plant community of the forest land with the "engineering plant closure" measure developed faster than that of the forestland with the "engineering plant closure" measure. Species are abundant. The results showed that there was no significant change in vegetation restoration with only closed measures. Vegetation restoration could be accelerated by plant or engineering measures, while horizontal bamboo grooves and Arbor irrigation were used. Soil and water conservation combined with grass can maximize vegetation restoration in soil and water loss areas.
