Abstract:Based on 3S technology, relationships and muti-scale effects between environmental factors and landscape pattern in the Wuyishan Scenery District was studied by using CCA (Canonical Correspondence Analysis). The results showed that the total eigenvalue of ordination axes increased with upscaling by 9.626, 7.814, 5.708, 4.019, 3.386 and 2.310 in six scales (30 m×30 m、90 m×90 m、150 m×150 m、210 m×210 m、300 m×300 m、450 m×450 m), respectively. The cumulative variance of landscape-environment relationship ranged from 97.3% to 98.8% in the first four ordination axes, and that of the first two ordination axes had an average of 89.4%. Landscape-environment correlation coefficients decreased at first and then increased. The average correlation coefficients between environment factors and landscape pattern were in order as canopy density (0.7989**) > humus thickness (0.7248**) > elevation (0.6083**) > slope (0.6132**) > longitude (-0.4064**) > soil thickness (0.3696**) > latitude (0.0614) > aspect (0.0295). Landscape types in Wuyishan Scenery District could be classified into three types, such as elevation related landscape, including bare land, water body, construction land, and farmland, soil related landscape, including Cunninghamia lanceolata forest, Pinus massoniana forest, broad-leaved forest, and human managed landscape, including Camellia sinensis plantation, economic forest, bamboo forest, shrub and grassland. Therefore, muti-scale effect existed between landscape pattern and environment factors, and the response law of environment factors to ordination axes could be scaling within six scales.
