内蒙古天然草地资源精细化气候区划研究

根据内蒙古107个气象站资料,利用梯度距离平方反比法,推算出内蒙古自治区气候数据的千米网格数据图形。根据内蒙古实际草原类型和畜种结构的分布规律,确定了内蒙古5类草原类型、6个产草量等级和5类主要放牧家畜地理分布的气候区划指标。利用气候区划指标,对栅格点气候数据进行分级,绘制了内蒙古自治区天然草原草地类型、产草量和主要放牧家畜地理分布的区划图,并分区进行评述。研究结果可为内蒙古畜牧业生产区域合理布局提供科学依据。

Study on Climatic Division of Natural Grassland in Inner Mongolia

According to the records from 107 meteorological stations in Inner Mongolia, using the Gradient Inverse Square Formula, the grid data in Inner Mongolia were calculated by interpolating under the GIS environment,and the resolution of grid data was 1 km×1 km in combination with the distribution characteristics of the grassland types and animal production structure in Inner Mongolia. The climatic regionalization indicators in Inner Mongolia are defined, which include five grassland types, six grassland yields grades and geographical distribution of five major grazing livestock. Using these climatic regionalization indicators, the climate data grades of each grid are classified, the regionalization thematic maps of grassland types, grassland yields grades and major grazing livestock in Inner Mongolia were drawn. Each kind of the regions was remarked, and suggestions for sustainable development were proposed. This study could provide scientific basis for the adjustment of agricultural structure and the optimal distribution of animal husbandry in Inner Mongolia grassland.
