摘要
利用2002年和2006年公路建设前后的两期遥感数据,分析了公路对沿线土地利用和景观格局的影响。结果表明:公路建设使公路用地面积增加了4.10km2,主要由侵占农业用地和沙地所导致;居民区、森林面积分别增加了1.12km2和0.08km2,其余土地利用类型面积有所减少;道路、居民区和森林的景观破碎化指数增加,农田、草地、灌木、沙地和水域下降;景观多样性指数增加,景观优势度降低。
This passage made use of the two remote sensing data of the highway construction in 2002 and 2006 to study the impact of the highway to the land use and the landscape pattern alongside the road. The result showed that the highway construction had led to the highway area raised by 4.1 square kilometers. The reason is almost invading and occupying fatal lands and sands. The residential area and forest area had increased by 1.12 square kilometers and 0.08 square kilometers, but the remaining land - use types had fell off to some extent. The landscape fragmentation of the road, resident and forest had increased. But the farmland, the grassland and the shrub had inclined. The landscape diversity increased and the landscape dominance inclined.
