| 英文摘要 | Nepal is a typically mountainous landlocked country. In recent years, land cover in Nepal has changed significantly due to climate changes, population growth and economic development. This study used four periods of land cover change data (1990-2000, 2000-2005, 2005-2010 and 2010-2015) produced by the object-oriented change detection method, to reveal the spatial patterns of land cover change and its driving forces in Nepal since 1990. The result showed that the total change area from 1990 to 2015 in Nepal is 1665.58 km(2), accounting for 1.13% of the land. Among these changes, forests, wetlands and permanent ice/snow presented a trend of decrease, whereas croplands, artificial surfaces and bare lands had been continuously increasing. The prominent land cover changes included mutual transformation between wetlands and croplands, wetland class inner shifts and the conversion of forests to croplands. These changes varied among different development regions and during different periods. In general, the intensities of land cover change in Eastern and Central Development Regions were higher than in other development regions. The annual change area was 59.26 km(2)/year during 1990-2000, reached to 98.44 km(2)/year during 2000-2005 and turned to slowly decline after 2005. The analysis and discussion indicated that major driving forces of land cover change in Nepal include climate changes, natural hazards, population growth, urbanization, economic development and government policy implementation. A comprehensive understanding of the relationships between land cover change and various driving forces in Nepal was given in this study, which would be valuable for policymaking, land planning, resource development and protection. Simultaneously, it could be also benefit to China's "Belt and Road Initiative." |
