Abstract

Interpretation of high resolution satellite imagery revealed various Land use/Land cover features in Pindrangi village, High resolution Satellite imagery was acquired from the goggle earth through Sas planet software, the data were acquired for the years 1984, 1994, 2004 and 2014. High resolution Satellite imagery was processed in Arc Map 10.4.1. Further an analysis of the decadal sequence imagery pertaining to decadal aimed at detecting the land use/land cover change has indicated that the plantation has phenomenally increased by 235.20 ha during the study period, at the same period, Crop land (Paddy) which occupied about 66.41 acres in 1984 has been reduced to 17.29 ha by 2014 mainly due to encroachment of plantation like Casurina/Eucalyptus and mango Scrubs area has decreased by 35.52 ha. The present study with the help of GIS and remote sensing (RS) is also a similar attempt in recording and quantifying change in land use and land cover in village level as spatial and temporal extents. The conversion of fallow land and Crop land into plantation around 12.91% in study area.

基于高分辨率卫星影像的品卓基村土地利用/覆被时空变化研究
高分辨率卫星图像解译揭示了Pindrangi村土地利用/土地覆盖的各种特征,通过Sas planet软件从goggle earth获取高分辨率卫星图像,数据采集年份为1984年、1994年、2004年和2014年。Arc Map 10.4.1处理了高分辨率卫星图像。此外,对土地利用/覆被变化的年代际序列影像进行分析发现,在研究期间,人工林显著增加了235.20 ha,与此同时,由于木木树/桉树和芒果灌丛等人工林的入侵,稻田面积从1984年的66.41亩减少到2014年的17.29公顷。本研究在GIS和遥感的帮助下,也是在记录和量化村级土地利用和土地覆盖的时空变化方面的类似尝试。研究区休耕还林率达12.91%。
