- 摘要:
- 为探究城市扩张与景观破碎化演变过程及其关联机制,以江西省南昌市为例,基于2000—2015年的土地利用数据,运用城市破碎指数(UFI)刻画建设用地的景观破碎化水平; 然后结合形态学空间格局分析(MSPA)和景观连接度分析量化了自然景观和耕地的景观动态演变过程; 最后采用格网分析探究了三者之间的空间自相关动态特征。结果表明:2000—2015年间南昌市共有273.26 km2的耕地及45.61 km2的自然景观转为建设用地,整体城市破碎度指数在研究期内由2.27上升至4.94; 耕地核心区数量在15 a时间内持续衰减,自然生境在前期变化平稳,随着城市化进程的加快,核心及桥接区不断减少,岛状斑块开始增加; 空间自相关分析显示,景观破碎度与自然生境、耕地平均连通概率三者呈负相关,景观破碎度与耕地、自然生境平均连通概率之间的高低聚集区域集中分布在城市扩张的主要区域。2000—2015年城市快速扩张导致的破碎化致使耕地及自然生境景观结构发生改变,景观连通性逐渐丧失。
- Abstract:
- To explore the evolution process of urban expansion and landscape fragmentation and its correlation mechanism, taking Nanchang City, Jiangxi Province as an example, based on the land use data from 2000 to 2015, the urban fragmentation index(UFI)was used to describe the landscape fragmentation level of construction land; then combined with morphological spatial pattern analysis(MSPA)and landscape connectivity analysis, the dynamic evolution process of natural landscape and cultivated land was quantified. Finally, grid analysis was used to explore the dynamic characteristics of spatial autocorrelation among the three. The results show that from 2000 to 2015, a total of 273.26 km2 of cultivated land and 45.61 km2 of natural landscape in Nanchang were converted to construction land, and the overall urban fragmentation index increased from 2.27 to 4.94 during the study period; the number of cultivated land core areas continued to decline in 15 years, and the natural habitat changed steadily in the early stage; with the acceleration of urbanization, the core and bridge areas continued to decrease, and the island patches began to increase; spatial autocorrelation analysis showed that landscape fragmentation was negatively correlated with the average connectivity probability of natural habitat and cultivated land; the high and low aggregation areas between landscape fragmentation and the average connectivity probability of cultivated land and natural habitat concentrated in the main areas of urban expansion. Fragmentation caused by the rapid urban expansion from 2000 to 2015 led to changes in the landscape structure of cultivated land and natural habitats, and the gradual loss of landscape connectivity.
