摘要
以遥感影像和实地调查相结合的方法对湖北省麻城市草地类型空间分布和特征进行了研究。根据中国草地分类系统,麻城草地可划分为6大类52型,主要分布于麻城市北部山区和东南部丘陵区。暖性灌草丛是分布最广、面积最大的一个类,除铁门岗乡外其他地区均有分布。热性灌草丛草地具有最高的牧草产量,平均干草产量达3 697.6 kg/hm^2。草地每平方米物种数4-17种,与20世纪80年代第一次草地调查结果相比没有明显变化,生物多样性保持良好。
Based on the remote-sensing image and field investigation, the characteristics and spatial distribution of natural grassland in Macheng county were studied. According to the ＂Chinese Grassland Classification System ＂, the grassland in Macheng county embraced 52 types in 6 classes and most of them distributed in north mountainous area and south-east hill area. The area of warm scrub-grassland class distributed in whole county except for Tiemen town. The hot season scrub-grassland had highest hay yield which was 3 697.6 kg / hm^2. The number of herbaceous plants in one square meter was 4-17which was similar to the results obtained in first grassland resources survey in the 1980 s.
