英文摘要	选取亚热带中尺度流域九龙江为研究对象,运用空间分析与统计分析方法,从全流域和河岸缓冲区尺度分别建立了九龙江流域2002年和2007年土地利用、景观格局与河流水质的关联.结果表明,2002年和2007年土地利用/景观格局-水质的关联基本一致,表现为建设用地面积比例与bOd5、nO 3--n、nH 4+-n和高锰酸盐指数呈负相关,与dO呈负相关;林地面积比例与nO 3--n、nH 4+-n和高锰酸盐指数呈负相关;耕地与nO 3--n、nH 4+-n和高锰酸盐指数呈负相关性.景观多样性指数(SHdI)与高锰酸盐指数、TP、nH 4+-n呈正相关,与dO呈负相关;最大斑块指数(lPI)与bOd5、高锰酸盐指数、TP和nH 4+-n呈负相关,而与dO呈正相关;斑块密度(Pd)与bOd5、TP和nH 4+-n呈正相关;但其它的景观指数与水质的关联无法被合理地解释.相对于全流域,缓冲区的土地利用面积比例和景观指数与河流水质的关联更为显著,因为大部分水质参数在缓冲区都能被更好地解释,表现在调整判定系数AdJuSTEd r2更大;土地利用面积比例比景观指数能够更好地预测水质,表现在大部分水质参数与土地利用面积比例有较好的相关关系.; Geospatial analysis and statistical analysis were integrated to link land use & landscape pattern and water quality in 2002 and 2007 at the entire watershed and buffer zone scale in the Jiulong River Watershed.Results show that the relationships between land use & landscape pattern and water quality in 2002 and 2007 were basically consistent,namely: ① Percentage of built-up area was positively correlated with BOD5,NO3--N,NH 4+-N and permanganate index,and negatively correlated with DO;percentage of woodland area was positively correlated with NO3--N,NH 4+-N and permanganate index;percentage of cropland area was negatively correlated with NO3--N,NH 4+-N and permanganate index.② SHDI was positively correlated with permanganate index,TP,NH 4+-N,and negatively correlated with DO at the entire watershed and buffer scale;LPI was negatively correlated with BOD5,permanganate index,TP and NH 4+-N,and positively correlated with DO at the entire watershed and buffer zone scale;PD was positively correlated with BOD5,TP and NH 4+-N;Most of the landscape pattern metrics was not the good predictors for water quality in study watershed.③ Water quality parameters in buffer zone area have more significant correlations with percentage of land use type areas and landscape pattern metrics,because most water quality parameters in the buffer zone can be better explained with greater adjusted coefficient of determination(Adjusted R2).④ Compared to landscape pattern metrics,percentage of land use type area can predict water quality better because most water quality parameters have more stable correlations.; 国家自然科学基金项目(40901100;40810069004);福建省自然科学基金项目(2009J01222)
