【摘要】:利用Iandsat遙感影像數(shù)據(jù)(TM、ETM+),結(jié)合氣象數(shù)據(jù),通過(guò)土地利用類型轉(zhuǎn)移矩陣,對(duì)和田地區(qū)該區(qū)域綠洲植被覆蓋面積和時(shí)空格局變化進(jìn)行分析,并結(jié)合和田地區(qū)政策、人口等因素對(duì)其驅(qū)動(dòng)因子進(jìn)行研究。結(jié)果表明:和田地區(qū)綠洲內(nèi)的林地、耕地和水域面積呈現(xiàn)先減少,后緩慢增加的趨勢(shì),受雪山融水供給的影響,該地區(qū)水域變遷幅度較劇烈;受全球大氣候與昆侖山南麓局地小氣候的影響,該地區(qū)氣溫呈現(xiàn)穩(wěn)定增加的趨勢(shì),而降水呈現(xiàn)先增加,后減少的趨勢(shì)。
[Abstract]:Based on Iandsat remote sensing image data (TM,ETM) and meteorological data, the changes of vegetation cover area and spatial and temporal pattern of oasis in Hotan area were analyzed by using land use type transfer matrix, and the policy of Hotan area was combined. Population and other factors to study its driving factors. The results showed that the area of forest land and water area in Hotan Oasis decreased first and then increased slowly. Under the influence of the global climate and the local microclimate in the southern foot of Kunlun Mountains, the temperature in this area is increasing steadily, while the precipitation is increasing first, then decreasing.
