Abstract
Land cover dynamics is a challenging and vigorous process that associates natural and human systems that have undeviating effects on atmosphere, water and soil which lead to many environmental problems worldwide. Urbanization is one of a major land cover change that is highly correlated with many environmental problems that need emphasis. This paper aimed to review and present level and effect of land use land cover changes, urbanization, factors affecting land cover change and application of geographic information system & remote sensing in monitoring land cover changes. Over the past 300 years, about 1.2 million kilometer square of forests and 5.6 million kilometer square of pasture and rangeland were replaced by other uses worldwide, while cultivated land increased by 12 million km2. In 1950, only 30 percent of the world population lived in urban settings, the fraction raised to 55% by 2018. This led to about roughly 60% of the ecosystem services are being destroyed or used in unsustainable ways worldwide. Population expansion, change of technology, high land value, corruption, lack of awareness, migration of people and political pressure are among major driving force of land cover changes. Geo-informatics technology specially GIS and Remote Sensing is found to be an excellent tool for study of land cover change that enables observation across large area of earth’s surface with low cost, better efficient and high accuracy. Therefore monitoring, analyzing and evaluation of land cover dynamics with the help of geo-informatics is decisive for improved management & characterizing land cover alteration processes, and determining its environmental consequences.

土地覆盖动态是一个充满挑战和活力的过程,它将自然和人类系统联系在一起,这些系统对大气、水和土壤具有不可缓解的影响,从而导致世界各地的许多环境问题。城市化是一个主要的土地覆盖变化,与许多需要强调的环境问题高度相关。本文旨在综述土地利用-土地覆盖变化的水平和影响、城市化、影响土地覆盖变化因素以及地理信息系统和遥感在土地覆盖变化监测中的应用。在过去的300年里,全世界约有120万平方公里的森林和560万平方公里牧场被其他用途所取代,耕地面积增加了1200万平方公里。1950年,世界上只有30%的人口生活在城市环境中,到2018年,这一比例上升到55%。这导致全球约60%的生态系统服务被破坏或以不可持续的方式使用。人口扩张、技术变化、土地价值高、腐败、缺乏意识、人口迁移和政治压力是土地覆盖变化的主要驱动力。地理信息学技术,特别是地理信息系统和遥感技术,被认为是研究土地覆盖变化的优秀工具,能够以低成本、高效率和高精度对大面积地表进行观测。因此,借助地理信息学对土地覆盖动态进行监测、分析和评估,对于改善管理和表征土地覆盖变化过程以及确定其环境后果具有决定性意义。关键词:土地利用;土地覆盖变化;城市化;GIS和遥感;环境版权所有(c)2020 Geosfera Indonesia Journal and Department of Geosfara Indonesia,University of Jember这部作品是根据知识共享署名共享类似4.0的国际许可证授权的
