【摘要】：耕地利用率能夠反映人類活動(dòng)對(duì)耕地的利用狀況,以遙感數(shù)據(jù)和地面調(diào)查數(shù)據(jù)為主要數(shù)據(jù)源,采用遙感抽樣、地理數(shù)學(xué)與3S技術(shù)相結(jié)合的方法對(duì)干旱區(qū)典型農(nóng)業(yè)區(qū)的耕地利用率進(jìn)行系統(tǒng)研究;結(jié)果表明:利用累計(jì)平方根法,并結(jié)合新疆農(nóng)業(yè)綜合區(qū)劃及新疆地勢(shì)資料,共將全疆分為12個(gè)耕地利用率類型區(qū)。天山北坡東部農(nóng)區(qū)耕地利用率為91.6%,伊犁河中游河谷平原農(nóng)區(qū)為91%,奇臺(tái)山前農(nóng)牧區(qū)和塔城盆地農(nóng)牧區(qū)耕地利用率僅為80%。天山北坡東部農(nóng)區(qū)土地利用效率較其他農(nóng)區(qū)要高。根據(jù)遙感抽樣方法測(cè)算得到的各分區(qū)的耕地利用率可見(jiàn),各分區(qū)的耕地利用率大多在90%以下�；谶b感抽樣的耕地利用率調(diào)查研究,可為進(jìn)行耕地中非耕地成分的整理提供依據(jù)。
[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.
