摘　　要：以2001—2020年MODIS遥感数据产品和河南省近30 a(1991—2020年)气候数据为数据源,基于主成分分析方法建立由植被覆盖度、生态释氧量、气溶胶光学厚度和度假气候指数构成的生态旅游适宜度指数(ESI),进而对河南省过去20 a的生态旅游适宜度进行评价研究。结果表明:近20 a,河南省植被覆盖度、生态释氧量整体呈现增长趋势,变化量分别为12.5%和191 g·m~(-2),相对变化率达到30.2%和32.3%。气溶胶光学厚度和度假气候指数整体呈降低趋势,变化量分别为-0.07和-1.65,相对变化率分别达到-13.6%和-2.25%,河南省生态环境整体呈现向好趋势。利用主成分分析构建的生态旅游适宜度指数(ESI)避免了因人为方法对权重设定不同所导致的结果偏差,使其更加具有客观性和可靠性,评价结果和目前河南省生态旅游景区分布情况整体一致,能客观反映区域内生态旅游适宜度的空间差异。生态旅游适宜度指数空间分布的高值区域集中在西部伏牛山区域和南部大别山区域,而低值区域集中在华北平原地区,2020年相比2001年的相对变化率为3%,生态旅游适宜度指数呈变好趋势。Using MODIS remote sensing data products from 2001 to 2020 and climate data from He′nan province over the last 30 years(from 1991 to 2020),an ecological tourism suitability Index(ESI)considering vegetation coverage,ecological oxygen release,aerosol optical thickness,and holiday climate index was established based on the principal component analysis method.The ESI was then used to evaluate the ecological tourism suitability in He′nan province over the past 20 years.The results show that over the past 20 years,the vegetation coverage and ecological oxygen release in He′nan province have generally shown an increasing trend with change rates of 12.5%and 191 g·m-2 as well as relative change rates of 30.2%and 32.3%,respectively.The aerosol optical thickness and holiday climate index show an overall decreasing trend with change rates of-0.07 and-1.65,and relative change rates of-13.6%and-2.25%,respectively,indicating an overall improvement in the ecological environment of He′nan province.The ESI constructed using principal component analysis avoids the bias in results caused by different weight settings due to subjective methods,and is more objective and reliable.The evaluation results are generally consistent with the current distribution of ecological tourism areas in He′nan province and can objectively reflect the spatial differences in ecological tourism suitability within the region.The high-value areas of the ESI are concentrated in the Funiu Mountain area of the west and the Dabie Mountain area of the south,while the low-value areas are concentrated in the North China Plain area.The change rate of the ESI in 2020 relative to that in 2001 was 3%,indicating an improving trend in the ESI.
