    摘要:

    旅游业在给目的地带来经济增长的同时,也会对其生态环境造成一定影响。既有研究多关注旅游业对生态环境的压力,而较少关注旅游业对目的地生态系统服务价值(Ecosystem service value ,ESV)的影响。为此,研究以“旅游社会—生态系统”为基础,构建了旅游业对目的地ESV的影响框架。以神农架为例,基于土地利用格局变化以及修正ESV价值当量,计算其2005—2018年ESV以及时空变化特点。通过地理加权回归(Geographically weighted regression,GWR)与增强回归树(Boosting regression tree,BRT)模型对距居民点距离、距景区距离、距酒店距离以及距道路距离等旅游因素对ESV的影响以及空间差异进行了研究,并得到以下主要结论:(1)神农架土地利用格局变化显著,耕地、林地、草地和未利用地面积总体减少,水域及建设用地面积总体增加。(2)神农架ESV呈逐年递增趋势,由2005年的33.58亿元增加至2018年的89.10亿元。11项生态系统服务功能所占价值比例稳定,以气候调节、水文调节、土壤保持及生物多样性为主。ESV在空间上呈现高度自相关性,表现为中部高、边界低的分布格局。(3)比较GWR与BRT结果,两者在旅游业因素对ESV影响的贡献上有差异。且GWR能从全局识别出影响ESV的空间差异以及影响效应的方向,而BRT则能更精准识别影响ESV变化的主要因素作用范围。

    Abstract:

    Tourism not only brings economic growth to the destination but also has a certain impact on its ecological environment. Existing studies have paid more attention to the pressure of tourism on the ecological environment but paid less attention to the impact of tourism on destination ecosystem service value (ESV). Therefore, based on the theory of tourism society-ecosystem, this study constructs a framework of the impact of tourism on ESV in the destination. Based on the change in land use pattern and the modified ESV equivalent, we calculated the ESV of Shennongjia during 2005—2018 and analyzed its spatio-temporal variation characteristics. Then we identified the influences of tourism factors on ESV, including distance to residential area (DRA), distance to scenic spot (DSS), distance to hotel (DH), and distance to road (DR). Finally, geographically weighted regression(GWR) and boosting regression tree(BRT) models were used to study the influences of tourism factors on ESV and spatial differences. The following conclusions were drawn: (1) the changes in land use pattern in Shennongjia were significant. The areas of cultivated land, forestland, grassland and unused land decreased to 2083.45hm2, 8018.62hm2, 285464.31hm2, 9474.68hm2 and 0hm2, respectively, by 2018. The areas of water and construction land increased. In 2018, it increased to 191.64hm2 and 926.79hm2, respectively. (2) The ESV of Shennongjia showed an increasing trend year by year, increasing from 3.358billion yuan in 2005 to 8.91billion yuan in 2018. From the perspective of ecological service functions, 11 ecosystem service functions accounted for a stable proportion of the ESV. The climate regulation, hydrological regulation, soil conservation and biodiversity accounted for approximately 70% of the value of ecosystem service functions. From the perspective of spatial and temporal evolution, ESV was highly autocorrelated, showing a high distribution pattern in the middle and low boundary. (3) The GWR results showed that DSS and DR had significantly positive influence on ESV, while DH and DRA had significantly negative influence on ESV, and the influence degrees were DSS, DRA, DR and DH, respectively. The BRT results showed that the factors of ESV change in descending order were DRA, DSS, DH and DR. (4) In terms of spatial heterogeneity, GWR could identify the spatial difference and the direction of the effect globally, while BRT could more accurately identify the scope of the main factors affecting the change in ESV.
