天津湿地景观格局动态变化
Dynamic changes of wetland landscape pattern in Tianjin, North China
摘要
Abstract
By using the TM images of Tianjin in 1999, 2003, and 2007 as the data source to acquire the wetland transition matrixes, and with CA-Markov model, this paper simulated the dynamic changes of wetland landscape pattern in Tianjin. The total area of wetland patch was increased from 3120. 89 km2 in 1999 to 3281. 34 km2 in 2007, then to 3297. 43 km2 in 2015 , and would be decreased to 3285. 78 km2 in 2023. The percentage of natural wetland would be decreased continuously from 33. 0% to 30. 2% , while that of constructed wetland would be increased to 69. 9% . Twenty variables were selected and divided into two types for establishing a driving factors index system. The analysis of driving force for the wetland landscape changes showed that the first principal component had positive correlations with GDP, per capita GDP, total fiscal revenue, secondary industry percentage, total population, non-agricultural population, freight turnover quantity, passenger turnover quantity, and port throughput, and negative correlations with primary industry percentage, tertiary industry percentage, and cropland area.关键词
