摘要
以花江示范区顶坛小流域为研究区,利用"3S"技术,研究了该流域2005年到2010年石漠化治理工程效益。根据小流域环境条件和治理效益分析结果,借鉴以往以皇竹草为主的石漠化草地建植经验,最后提出优化草地群落配置、以皇竹草等优势草种根治杂草、发展草地生物多样性等对策。
Being the last defense of karst mountain ecological environment,the grass system is irreplaceable in rocky desertification management.Dingtan drainage of Huajiang Pilot was taken as an example.Combined with 3S techniques,the rocky desertification management benefit was studied in 2010 to 2005.According to the benefit result as well as drainage natural situation and former relevant experiences with Ponnisetum hydridum grassland,a strategy that Ponnisetum hydridum should be cultivated to control weeds and develop biodiversity was suggested to provide reference for control project of rocky desertification area in dry spring-wet summer dry karst valley with mid-intense rocky desertification.
