摘要: 以海伦市1986年,1995年和2007年3期TM影像为基础数据,在RS与GIS技术支持下,运用马尔科夫转移矩阵、单一土地利用类型动态度和景观空间格局分析方法对沿海市土地利用变化、景观格局特征进行研究,并分析了土地利用变化的驱动力。结果表明,①旱田和水田面积一直处于增长状态,增长速率由快变缓,主要由林地、草地和未利用土地转换而来。②林地、草地和未利用土地面积持续下降;城镇建设用地和农村建设用地的面积一直保持着增加态势,增长速率由缓变快,使得土地利用强度有所上升。③景观格局变化主要表现为,优势度整体上升、景观多样性整体呈现下降的趋势,城乡建设用地的类斑近圆指数最大,林地、未利用土地和水域斑块破碎度增加。④人为因素中的人口增长、经济发展、政府生态环境保护和农业可持续发展的政策在土地利用变化中起重要作用。该研究对于合理利用土地资源和农业可持续发展具有重要意义。

Abstract: Based on TM image data of Hailun during 1986-2007, supported by RS and GIS technology, the landuse change and landscape pattern characteristics were studied at Hailun County through the Markov conversion matrix, a single dynamic degree of landuse and landscape spatial pattern analysis, and the driving force of landuse change was analyzed. The results showed that:① The area of dry farming land and paddy field has been in a growth state, but growth rate slowed down, the fields are mainly from forest land, grassland and unused land.②Forest land, grassland and unused land area continued to decline; urban construction land and rural construction land area remained increasing with its rate growing quickly. ③Landscape pattern changes were mainly as follows: the degree of dominance increased integrally and the landscape diversity decreased, the mean proximate circular indexes of urban and rural construction land was the greatest. Woodland, patches fragmentation of unused land and waters increased.④ Humaous factors in population growth and economic development plays an important role in land-use change.
