    摘要:

    [目的] 探究旅游型乡村景观格局演变过程及生态系统服务价值(ESV)响应,为合理规划乡村景观资源提供科学依据。[方法] 以无锡市太湖国家旅游度假区马山半岛为例,选取1984—2020年5期遥感影像进行景观分类,计算土地利用动态度、转移矩阵、景观格局指数。基于当量因子法评估生态系统价值(ESV),并计算各景观类型ESV敏感性指数。此外,运用SPSS对ESV与景观格局指数进行相关性和回归分析。[结果] ①1984—2020年,马山半岛景观格局变化显著,各类景观转换频繁。建设用地、灌草丛面积增加,阔叶林地、水系、裸地和其他用地缩减。景观格局趋于破碎化、复杂化,且连通性减弱。②马山半岛水系、阔叶林地ESV的比例最大,对区域ESV贡献最高。ESV呈下降趋势,累计缩减7.08×105元,且各单项ESV均降低,调节服务缩减最严重。③马山半岛ESV与景观格局指数相关性显著,但各指数影响程度不同。[结论] 随着旅游业建设发展,度假区马山半岛景观格局、ESV变化显著,且二者相关性显著,通过调整关键景观格局特征可提高生态系统服务效益。

    Abstract:

    [Objective] The evolution process of rural landscape tourism patterns and the response of ecosystem services value were studied in order to provide a scientific basis for the rational planning of rural landscape resources.[Methods] Five remote sensing images of Mashan Peninsula, Taihu Lake National Tourism Resort in Wuxi City, Jiangsu Province from 1984 to 2020 were selected for landscape classification. Land use dynamic degree, transfer matrix, and landscape pattern indexes were calculated. The ecosystem services value (ESV) was evaluated based on the equivalent factor method. The coefficient of sensitivity for each landscape type was calculated. Additionally, correlation analysis and regression analysis between ESV and landscape pattern indexes were carried out using SPSS.[Results] ① From 1984 to 2020, the landscape pattern of Mashan Peninsula changed significantly, and the various types of landscape changed frequently. The area of construction land and shrubs and grass increased over time. In contrast, the area of broad-leaved forest land, bodies of water, bare land, and other land decreased. The landscape patterns tended to be fragmented and complicated, and connectivity weakened over time. ② Mashan Peninsula water system and broad-leaved forest land had the largest proportion of ESV, and contributed the most to regional ESV. ESV declined over time, with a cumulative reduction of 7.08×105 yuan. The value of each individual ecosystem service decreased, and the reduction in value of regulating service was the most significant. ③ ESV was strongly correlated with the landscape pattern index in Mashan Peninsula, but the degree of influence for each index was different.[Conclusion] With the development of tourism, the landscape pattern and ESV of Mashan Peninsula have changed significantly, and the correlation between the two was significant. Ecosystem service benefits can be improved by adjusting key landscape pattern characteristics.
