“…Usually, there are two quantification methods: physical quantity and value quantity. Researchers will choose net primary productivity (Li et al, 2014), carbon storage (Li and Geng, 2023; Zhang et al, 2015), soil retention (Zhang et al, 2021), water production ( Zhao et al, 2022) and sediment yield (Yuan et al, 2022) as ecosystem services to be assessed using models. For instance, the InVEST model has been used to measure water conservation, carbon sequestration, soil retention, habitat quality, and more (Zhang et al, 2022; Zhou et al, 2010).…”

Since the beginning of the 21st century, recognizing the need for sustainable development and the protection of ecosystems, the United Nations and international agencies have been actively promoting the protection of the natural environment. The construction of ecological networks (EN), as one of these efforts, emphasizes the connectivity between natural patches and their ability to support ecosystem services (ES). Currently, constructing ecological networks using ecosystem services as a comprehensive evaluation criterion has become one of the important ways to maintain sustainable ecosystems. Karst regions have received much attention due to their fragile ecosystems, and this paper reviews articles from around the world that have studied ecosystem services and ecological networks in these regions. It found that this research is gradually maturing, although the number of published articles on research related to ecological networks is relatively small, with the largest number of papers taking the Chinese Karst region as a study area. Indicator factors for the construction of ecological networks in this region are usually based on ecosystem services, but they are usually not considered comprehensive enough, e.g., the trade-offs and synergies among ecosystem services are rarely considered. At the same time, the construction of ecological networks requires dynamic monitoring and optimization on a larger scale in order to provide assistance for longer-term environmental protection.

“…The suitable hydrothermal environment enriches the plant resources in Guizhou Province, and make a wide distribution of evergreen-deciduous broad-leaved mixed forest. Among them, the evergreen plants mainly include the Quercus, Neolitsea, Sloanea, and the deciduous plants are mostly the Cornus, Cerasus, Carpinuspubescens, and Platycarya (Li et al, 2022b).…”

“…Differences in spatial distribution of soil physical and chemical properties affected the growth suitability of plants, leading to the spatial heterogeneity of plant species and richness (Zhang et al, 2013), and thus the increase in plant diversity. In addition, human disturbance was an important driver for plant diversity decrease (Li et al, 2022b). The steep slope prevented the human disturbance on karst peaks to some extent.…”

Ecological connectivity in landscapes is crucial for plant diversity conservation. The barrier risk to ecological connectivity represents the risk to ecological connectivity loss or weakening, resulting from the barrier to biological information exchange among habitats. Therefore, clarifying the barrier risk to the ecological connectivity of plant diversity in space can reveal the spatial impacts of reduced ecological connectivity on plant diversity. This study analyzed effects of karst peak, river network, arable land, and impervious surface on plant diversity in karst natural, countryside, urban, and island landscapes in Guizhou Province with fragile environment. Then, we calculated the barrier distance of ecological connectivity to reveal the barrier risk to the ecological connectivity of plant diversity in space. The results showed that karst peak was the source of high plant diversity, and plant diversity could diffuse about 400 m around karst peaks. River network and arable land enhanced the connectivity among karst peaks to maintain plant diversity, and the effect on enhancing the connectivity was about 300 m and 450 m, respectively, while the weakening effect of impervious surface on connectivity was about 350 m. Based on the distance for plant diversity diffusing around karst peaks, the barrier distance of ecological connectivity was determined by the combination type of river network, arable land and impervious surface in landscapes. From low to high, the barrier risk to the ecological connectivity of plant diversity was about 1,110 m in the combination of river network and arable land, about 790 m in the combination of river network, arable land and impervious surface, about 520 min the combination of arable land and impervious surface, about 400 m in the combination of river network and impervious surface. Our findings clarify the barrier risk to the ecological connectivity of plant diversity in space, and provide a scientific basis for plant diversity conservation from the perspective of ecological connectivity.
