【摘要】：耕地利用率能够反映人类活动对耕地的利用状况,以遥感数据和地面调查数据为主要数据源,采用遥感抽样、地理数学与3S技术相结合的方法对干旱区典型农业区的耕地利用率进行系统研究;结果表明:利用累计平方根法,并结合新疆农业综合区划及新疆地势资料,共将全疆分为12个耕地利用率类型区。天山北坡东部农区耕地利用率为91.6%,伊犁河中游河谷平原农区为91%,奇台山前农牧区和塔城盆地农牧区耕地利用率仅为80%。天山北坡东部农区土地利用效率较其他农区要高。根据遥感抽样方法测算得到的各分区的耕地利用率可见,各分区的耕地利用率大多在90%以下。基于遥感抽样的耕地利用率调查研究,可为进行耕地中非耕地成分的整理提供依据。
[Abstract]:The utilization rate of cultivated land can reflect the utilization of cultivated land by human activities. Remote sensing sampling is used as the main data source of remote sensing data and ground survey data. The utilization rate of cultivated land in typical agricultural areas in arid area is studied systematically by the combination of geography mathematics and 3s technology. The results show that the method of accumulative square root is used in combination with the agricultural comprehensive regionalization of Xinjiang and the topographic data of Xinjiang. The whole Xinjiang is divided into 12 cultivated land use rate types. The utilization ratio of cultivated land is 91.6 in the eastern part of the northern slope of Tianshan Mountain, 91 in the plain area in the middle reaches of Yili River, and 80 in Qitai Mountain and Tacheng basin. The land use efficiency of the eastern agricultural area on the north slope of Tianshan Mountain is higher than that of other agricultural areas. According to the method of remote sensing sampling, the cultivated land utilization rate of each district can be seen, most of which are below 90%. The investigation and study of cultivated land utilization rate based on remote sensing sampling can provide the basis for the consolidation of cultivated land non-cultivated land composition.
