摘要
为区域可持续发展提供参考,采用ArcGIS9.3平台解译并提取仁怀市2000-2010年的土地利用变化数据,研究了仁怀市土地利用变化对陆地植被碳储量的影响。结果表明:耕地、牧草地、水域和未利用地呈递减趋势,林地和建设用地呈递增趋势;大量耕地、未利用地和牧草地转化为林地,部分林地和未利用地转化为耕地,其他地类主要转入建设用地。植被碳储量结构为林地>耕地>牧草地,植被碳储量从2000年的147.56×104t提高到2010年的173.26×104t,增加27.70×104t,退耕还林、还草和未利用地开发使植被碳储量增加59.10×104t,林地开发使植被碳储量减少8.61×104t。林地是影响仁怀市植被碳储量的主要因素。
Based on data from remote sensing TM/SPOT imageries in 2000and 2010in Renhuai,the process of land use/cover change were explained and analyzed by ArcGIS 9.3technology to provide a reference for regional sustainable development.Results:Cultivated land,grassland,water and unused land decreased,woodland and construction land increased;a large number of cultivated land,unused land and grassland turned into forest land,woodland,and unused land turned into cultivated land,construction land received other lands.The structure of carbon storage was woodland>arable land>grassland.The vegetation carbon storage increased from 147.56 104t to 173.26 104t during the study period,increased by27.70 104t.The vegetation carbon storage increased by 59.10 104t because of farmland changing into forest,grassland,and the development of unused land.The vegetation carbon storage decreased by 8.61×104t because of woodland changing into farmland.The main factor affecting vegetation carbon storage was woodland
