河南省天然草地资源区划的研究

Studies on Henan Province Rangeland Resource Regional Planning

以2018年河南省草地清查结果为基础,依据河南气候、地形地貌、草地类型和利用方式的多样性特点,对河南省天然草地进行区划,为河南省天然草地的保护和合理化利用提供依据。按照简单明了和容易实际操作的原则,依据气候、地形和地貌的明显分界线进行划区,使同一区的气候、地形地貌和草地类型尽可能保持一致,草地区的命名方法为:地形地貌+草地类。根据区划原则,河南省天然草地可分为4个类,30个型,5个草地资源区,分别为:豫北山地暖性灌草丛以及低地草甸区,豫西山地暖性灌草丛、低地草甸类和山地草甸区,平原农区低地草甸暖性灌草丛区,淮南山地热性灌草丛和低地草甸区;黄河滩区低地草甸和暖性灌草丛区。河南天然草地区划结果有利于针对不同气候条件、土壤条件和植被条件进行改良、利用和保护,有利于发挥天然草地的多样化功能,挖掘其巨大的生产潜力,能把宝贵资源转化为生产力,大力发展河南省以草牧业为核心的多种经济发展。

Based on the survey results of natural rangeland of Henan province,rangeland resource regional planning was designed to provide a theoretical basis for scientific conservation and rational utilization of the resources in the future according to diversity characters (including climate,landscape,rangeland type,utilization methods).Rangeland regional planning was simply and practically made to keep uniformity of climate and landscape for same zone and to maintain differences for different zone.Naming method of natural rangeland for different division was expressed as:landscape +rangeland type.Natural rangeland of Henan province could be merged into 5 divisions as following:1.North Henan mountain warm-temperate shrub tussock and lowland meadow zone.2.West Henan mountain warm-temperate shrub tussock,lowland meadow and upland meadow zone.3.Plain rural lowland meadow and warm-temperate shrub tussock zone;4.South Henan tropical shrub tussock and lowland meadow zone.5.Yellow river beach lowland meadow and warm-temperate shrub tussock zone.Henan rangeland resource zoning would help expanding diversified functions by protection,recovery and utilization according to different climate,soil and plant vegetation.Zoning of rangeland would also exploit great production potential of rangeland resources and convert them into powerful productivity of local multiple economy development with grassland husbandry as a core component.
