豫西地区天然草地分布及主要生产力研究

Distribution and Main Productivity of Natural Grassland in Western Henan Province

为准确掌握豫西地区天然草地的面积、产草量、载畜量及主要生产力状况,以2018年河南省天然草地资源调查数据为依据,采用遥感影像和野外实地调查方法,对天然草地的类型、分布、植被种类及主要生产力进行了研究。结果表明,豫西地区共有3个草地类及16个草地型,天然草地面积为16.13万hm2,占全省天然草地的30.89%,是河南省天然草地的主要分布地。

In order to accurately grasp the area,grass yield,stock capacityand main productivity of natural grassland in western Henan province,remote sensing images and field survey methods were used to study the types,distribution,vegetation types and main productivity of natural grasslandbased on the survey data of natural grassland resources in Henan province in 2018.The results showed that there were 3 grassland classes and 16 grassland types in the west of Henan province.As the main distribution region of natural grassland in Henan province,western Henan has 1.613×105 hm2 natural grassland area,accounting for 30.89%of natural grassland in Henan province.
