Abstract: The influence of landscape pattern on w ater quality w ill change depend ing upon scale, so it is mean ingful to probe how changes in landscape pattern influence water quality at differing spatialtemporal scales. Forw aterenvironment protection of reservoir watersheds in Shenzhen city, this paper took Xili reservoir watershed and its subwatersheds as research areas. This paper studied the influence of landscape spatial differences on w ater quality at differing tem poral and spatial scales. At the temporal scale, this paper chose water quality monitoring data at theX ili reservoir outlet in 2000 and 2001, which wasm ore heav ily influenced by nonpoint pollution than point pollution. Spatially, due to the lmi its ofdata, this paper divided data into two spatial scales: the Xili reservoir watershed and its subwatersheds. The
