摘要:

为分析丹江口库区消落带土地利用空间格局及土地资源特点,基于2013年丹江口水库调水前无人机采集的库区0.5 m数字正射影像,对库区蓄水前的土地利用现状进行遥感监测。结合行政区划图和1∶50 000数字高程模型提取的150,160,163.5,170 m水位淹没线、坡度图,采用空间分析与地理统计方法,研究了丹江口库区调水前的土地利用现状特点。结果表明150~160 m,160~170 m消落带面积分别为227.1 km2,194.3 km2;消落带主要分布在淅川、丹江口、郧县;耕地是消落带区域内最主要的用地形式,且主要分布在淅川。监测结果为丹江口库区消落带管理提供了数据基础。

Abstract:

To analyze the spatial pattern of land-use and characteristics of land resources in Danjiangkou water-level-fluctuating zone, land-use status quo is monitored through remote sensing based on 0.5 m Digital Orthphoto Map in the reservoir area acquired through unmanned aerial vehicle by 2013 before impoundment of the reservoir area. Moreover, the characteristics of land-use status are studied using spatial analysis and geostatistical methods in association with administrative map, slope map and 150 m, 160 m, 163.5 m, 170m water flooding lines extracted from 1∶50 000 Digital Elevation Model. Results show that the areas of water-level-fluctuating zone are 227.1 km2 and 194.3 km2 at elevation 150-160 m and 160-170 m, respectively. Water-level-fluctuating zones are mainly distributed in Xichuan, Danjiangkou and Yunxian County. Arable land is the main land form in the fluctuating zone and is mainly distributed in Xichuan. The monitoring results provide a data basis for the management of Danjiangkou water-level-fluctuating zone.

Key words: Danjiangkou Reservoir, water-level-fluctuating zone, land-use, spatial and geostatistical analysis, UAV remote sensing
