中文摘要:
      面向草地畜牧业格网化管理的区域发展需求,以新疆新源县为研究对象,以家畜存栏统计数据为基础,结合 城镇距离、村庄距离、河流距离、道路距离、海拔和湿润度等地理空间数据,运用格网化技术,对新源县家畜密度进行 空间格局分析。结果表明:新源县家畜活动密度平均为430标准羊单位/km2,但随着相对城镇、村庄距离的增加,海拔 高度和气候干旱程度的增加,家畜活动密度呈明显降低的趋势。这种空间格网化家畜分布数据比平均密度数据更易直观 表达家畜的真实分布状况。基于家畜活动密度,可以将新源县家畜放牧划分为:稀扰区、适度区、轻扰区、中扰区和重 扰区,其家畜活动密度分别为:110 ~ 300标准羊单位/km2、300 ~ 440标准羊单位/km2、440 ~ 570标准羊单位/km2、 570 ~ 720标准羊单位/km2和720 ~ 980标准羊单位/km2。
英文摘要:
      In this paper, to satisfy the need of regional development for the grassland animal husbandry grid handling management, with Xinyuan county as a case study, on the basis of livestock amount of statistical data, combining with the geographic spatial information data such as villages and towns of distance, road distance,river distance, elevation and moist, using the grid handling technology, to analysis the space distribution pattern of livestock activities density in Xinyuan county. The analysis results show that: the average density of Xinyuan county livestock activities is 430 standard sheep unit/km2, but with the increase of distance away from the villages and towns, and the increase of altitude and climate drought degree, the density of livestock activity decreased significantly. At the same time, we can divide Xinyuan county livestock grazing region into different partition according to the relative density. The grazing dilute district livestock density is 110-300 standard sheep unit/km2, moderate grazing area is 300-440 standard sheep unit/km2, light grazing disturbance area is 440-570 standard unit/km2, sheep grazing disturbance in the area is 570-720 standard sheep unit/km2, heavy grazing disturbance area is 720-980 standard sheep unit/km2.
