摘  要:
以海峡西岸经济区(海西区)为研究区,运用GIS、遥感技术和数理统计等方法,分析了1992—2008年海西区森林格局及其变化特征,采用典范对应分析(CCA)考查了环境因子对森林格局变化的影响。结果显示:海西区森林资源丰富,占区域总面积的61.40%,但其地理分布极不均匀,具有明显的区域和高程梯度差异;1992年以来海西区森林呈下降趋势,由1992年的8.93万km2降至2008年的8.83万km2,变化趋势在区域和高程梯度上存在明显差异,武夷山中西部森林的减少趋势较为明显;影响海西森林格局变化的主要环境因子有:气温、日照时数、人均GDP和降水量,蒸发量和人口密度对森林格局变化的影响相对较弱。

摘  要:
With the utilization of RS/GIS techniques and mathematical statistics method,the forest pattern and its variation characteristics from 1992 to 2008 in Western Taiwan Straits Economic Zone were analyzed,and the influence of the environmental factors on forest pattern changes was discussed by canonical correspondence analysis.The results showed that the forest resources in Western Taiwan Straits Economic Zone was abundant,accounting for 61.40% of the total area,while the distribution was extremely uneven with a significant difference of area and elevation gradient.The forest area decreased from 893 000 km2 in 1992 to 883 000 km2 in 2008,the changes between area and elevation gradient were obvious,and the decrease trend in Midwest of Wuyi Mountain was comparatively significant.The main environmental factors affecting forest pattern changes were temperature,insolation duration,per-capita GDP and precipitation,while the effect of evaporation and population density was relatively insignificant.
