摘要
对武夷山风景名胜区景观类型空间关系及其尺度效应研究结果表明 ,景观类型空间关系存在尺度效应 ,尺度变化对破碎化程度高的景观类型空间关系影响较大 ,而对破碎化程度低的景观类型空间关系影响较小。研究景观类型空间关系时其取样尺度不宜太大 ,武夷山风景名胜区以 2 0 0m× 2 0 0m取样尺度最佳。武夷山风景名胜区景观类型空间关系特征为低海拔高度区呈现出以居民点为中心的由农田、河流等向周围扩散的干扰景观格局 ,而中高海拔高度区则呈以近成熟。
The spatial relationships of landscape types and the scale effects in the Scenery District of Wuyi Mountain are analyzed in this paper. The results show that the relationships of landscape types are affected by different sampling scales. The higher the fragmentation degrees of the landscape types are, the greater the effects of sampling scales on their spatial relationships will be, while the sampling scale effects will be smaller if the fragmentation degrees of landscape types are lower; the sampling scale should not be too large in the research of spatial relationships of landscape types. For the Scenery District of Mt. Wuyi, the sampling scale of 200m×200m is the best; the characteristics of spatial relationships of landscape types in the Scenery District show that the landscape pattern in low elevation is controlled by the disturbance regime, which comes from residential area, spreads through farmland and river, and in the middle or high elevation, the landscape pattern is controlled by the natural Pinus massoniana forest which is mainly made of near ripe and over ripe forests of Pinus massoniana .
