摘要

[目的]综合分析1990-2014年甘肃省白龙江流域土地利用变化及其对人类活动的响应，以期为该区未来的土地利用优化提供参考。[方法]基于1990年，2002年，2014年3期遥感影像解译获取的土地利用数据，计算土地利用变化速度、土地利用转移矩阵和土地利用程度。[结果]1990-2014年流域的综合土地利用动态度从10.24%增长到17.59%；1990-2014年流域的土地利用类型变化以草地、耕地和林地的转换为主；1990-2002年流域内各县（区）的土地利用程度综合变化指数介于1.38~6.65，而2002-2014年流域内各县（区）的土地利用程度综合变化指数介于-15.43~0.17。[结论]1990-2014年流域人类活动对土地的利用由简单索取开发型转变为保护与生态建设型，从破坏性、粗放式和低利用效率向保护性、集约式和高利用效率发展。

Abstract

[Objective] Land use change and its response to human activities were analyzed comprehensively in Bailongjiang Watershed of Gansu Province during 1990-2014

to provide reference for land use optimization in the future.[Methods] Based on the land use data interpreted from the remote sensing images of 1990

2002 and 2014

this paper calculated the rate of land use change

the direction of land use transformation and the degree of land use in Bailongjiang watershed of Gansu Province during 1990-2014.[Results] The integrated dynamic degree of land use of the whole watershed increased from 10.24% to 17.59%. The change of land use types was mainly in grassland

arable land and forestland of the watershed during 1990-2014. Comprehensive change index of land use degree of all districts ranged from 1.38~6.65 during 1990-2002 to -15.43~0.17 during 2002-2014.[Conclusion] It proved that land use by human activities had converted from simple development to ecology prone one. Land use shifted from the types of destructiveness

extensive-type and low efficiency to the ones of conservation

intensive-ways and high efficiency in Bailongjiang watershed of Gansu Province during 1990-2014.
