LAND COVER TRANSITION IN THE SHUANGHE NATURAL RESERVE AREA, HEILONGJIANG PROVINCE: A Study Based on Landscape Transfer Matrix
-
摘要: 选择2005与2012年两期遥感影像，基于RS/GIS技术和转移矩阵数学模型，从景观转移方面对保护区景观要素时空变化进行定量分析，探讨了双河自然保护区在7年内土地利用格局及土地转化规律.结果表明，林地、灌木及草地之间转化较为突出，与保护区的环境因素有直接关系.沼泽、水域、居民地及裸土地因其面积基数小，类间转化量较小.旱田较活跃，除居民地外，其余6类景观都有面积转化为旱地.林地和草地相互转化较为活跃，灌木和林地相互转化较为活跃.研究结果可以为保护区的生态治理和可持续发展规划提供科学依据.Abstract: Based on RS/GIS technology and transfer matrix data model, the RS images of the Shuanghe Nature Reserve Area in two historic periods (2005 and 2012) are selected for quantitative analysis of the land use changes and landscape transfer regularity in the area during the 7 years. The study shows that the conversion between forestland, shrub and grassland is obvious, which has a direct relation with the environmental factors in the area. Because the base areas of swamp, water, resident place and bare soil are small, the transition between them is limited. Dry farmland changed notably during this period. Except for resident place, the rest 6 types of landscape areas are all partially converted into dry land. Active mutual transition took place between forestland and grassland, as well as shrub and forestland. This result would hopefully provide a scientific basis for the ecological management and sustainable development planning of the reserve area.
