    摘要:

    以內(nèi)蒙古自治區(qū)包頭市為研究區(qū),,選取2006、2010、2016年相同月份遙感影像,,結(jié)合包頭市土地利用數(shù)據(jù),,將包頭市景觀類型劃分為林地,、草地,、水體,、耕地,、建設(shè)用地,、其他用地共6類,進(jìn)行景觀格局動(dòng)態(tài)度變化分析,、轉(zhuǎn)移網(wǎng)絡(luò)分析,、變化空間集聚特征分析、重心轉(zhuǎn)移分析,、景觀格局指數(shù)變化分析和景觀格局演變驅(qū)動(dòng)力分析,。結(jié)果表明,2006—2016年市域景觀特征發(fā)生了較大變化,,其中2006—2010年其他用地景觀類型的減少速度高達(dá)19.48%,,10年間建設(shè)用地的增加速度從1.3%增至2.76%,在2010—2016年有15.19%的耕地轉(zhuǎn)化為草原景觀,,3.79%的耕地轉(zhuǎn)化為建設(shè)用地,;10年間景觀變化呈現(xiàn)點(diǎn)狀分布,主要分布在耕地密布,、草地破碎的農(nóng)業(yè)耕作區(qū)和不同景觀交替的邊緣,;2006—2010年間,其他用地中的北部裸土地經(jīng)過生態(tài)治理面積減少,,其重心向東南移動(dòng)73.79km,;景觀分割指數(shù)、香農(nóng)多樣性,、香農(nóng)均勻性等呈減小趨勢(shì),,尚未形成優(yōu)勢(shì)景觀,景觀破碎度加??;通過景觀格局驅(qū)動(dòng)力分析發(fā)現(xiàn),景觀變化密集度與NDVI具有相關(guān)性,。

    Abstract:

    Taking Baotou City of Inner Mongolia as a research area, the remote sensing images of the same month in 2006, 2010 and 2016 were selected. Combined with the land use data of Baotou City, the landscape types of Baotou City were divided into six categories, namely, forest land, grassland, water body, cultivated land, construction land and unused land. And the analysis of landscape pattern dynamics change, transfer network, landscape change spatial aggregation characteristics, center of gravity transfer, landscape pattern index change and landscape pattern evolution driving force were analyzed. The results showed that the characteristics of the urban landscape had undergone profound changes during the decade of 2006—2016. In 2006—2010, the rate of reduction of unused land was as high as 19.48%, and the growth rate of construction land for ten years was increased from 1.3% to 2.76%. In 2010—2016, totally 15.19% of the cultivated land was converted into grassland landscape, and 3.79% was converted into construction land. In the past ten years, landscape changes were distributed in Baotou City. The landscape changes were mainly distributed in the agricultural farming areas where the cultivated land was densely covered with grassland and the interlaced edges of different landscapes. In 2006—2010, in the unutilized land, the bare land in the north was ecologically treated, the area was reduced, and the center of gravity was moved 73.79km to the southeast. The landscape segmentation index, the aroma diversity, the fragrance uniformity, etc. were decreased, and the dominant landscape was not yet formed, and the landscape fragmentation was intensified. Through the analysis of landscape pattern driving force, it was found that the intensity of landscape change was related to NDVI. 
