摘要:我国牧草适宜性和牧草区划研究比较欠缺。20世纪80年代中期,洪绂曾先生曾组织国内相关科学家撰写了《中国多年生栽培草种区划》。之后,只有零星文章论述某些牧草的生态适宜性。近些年,随着肉食需求的增加,牧草产业迅速发展。因此,以计算机信息技术、地理信息技术、数据库技术等技术为支撑,采用C/S模式建立一套完善的我国主要栽培牧草适宜性评价系统。本数据集以温度、水分、土壤等自然要素的空间数据库为基础,通过GIS的统计学分析方法,以牧草生物学特性为主,同时联系牧草实际生产情况,并综合考虑各因子最后获得不同牧草的适宜性分布图,在最大限度上做到理论上科学,模拟结果上准确。明确了中国主要栽培牧草全国范围内生态适宜性的分布区,共涉及34种主要多年生栽培牧草、10种一二年生牧草。成果能够在一定程度上弥补我国多年生栽培牧草区划、栽培引种方面的技术短板,对今后各地区牧草种植起到科学的指导作用。

Abstract & Keywords
Abstract: Forage adaptability and regional distribution in China is understudied. Since Hong Fuceng’s edited collection Regional Mapping of Perennial Grasses in China published in later 1980s, only a few articles have explored the ecological adaptability of forages. In recent years, the forage industry developed rapidly with the increasing demand for meat. Supported by computer information technology, geographic information technology and database technology, we established a complete system for evaluating forage suitability by using C/S model. Based on the spatial data of natural elements such as temperature, moisture, and soil, we used the GIS statistical analysis method, and comprehensively considered the biological characteristics of forage grass, the actual grass production, as well as other factors to obtain the adaptability/distribution maps of different forages that are theoretically sound and with accurate simulation results. The dataset clarifies the distribution of major ecologically adaptable forages in China, covering 34 species (genera) of perennial forage grasses and 10 species of annual or biennial forage grasses. The outcomes, to a certain extent, make up the technical deficiency concerning the cultivation and introduction of perennial forage grasses in China, guiding forage planting in different regions.
