“…where TI i is the threat level of human activities from construction land to ecological land in region i, R is the total number of construction land pixels within a certain distance to pixel j, IC r is the influence coefficient of the construction land pixel r measured by the standardized value of night light brightness, dj r is the distance between ecological land pixel j and construction land pixel r, and d jmax is the maximum effective distance of human threat reach across space, that was set to 5 km [71]. ECC is calculated by integrating ecological land loss index and TI of construction land.…”

Regional land use transitions driven by the adaptive reconciliation of existing land use conflict with socioeconomic development can lead to positive economic effects as well as new land use conflict. Although research on land use transition has progressed considerably, limited studies have explored the spatiotemporal dynamic pattern of land use conflict during the land use transition period. Previous evaluation approaches on land use conflict that mainly focus on status or potential conflict lack conflict intensity evaluation during the land use transition process. A new spatially explicit evaluation framework of land use conflict that directly examines three aspects of conflict, namely, ecological and agricultural (EAC), agricultural and construction (ACC), and ecological and construction (ECC) land conflicts based on ecological quality and agricultural suitability, is proposed in this study. The spatiotemporal dynamic pattern and driving factors of land use conflict in the Yangtze River Economic Belt of China in the period of 2000–2018 are evaluated. The results indicated that comprehensive land use conflict (CLUC) intensity slightly decreased by 9.91% and its barycenter showed a trend toward the west during 2000–2018. ACC is the most drastic conflict among the three aspects of conflict. The mean intensity of ACC reduced remarkably by 38.26%, while EAC increased by 33.15% and ECC increased by 28.28% during the research periods. The barycenter of EAC moved toward the east while the barycenter of ACC and ECC moved toward the west. The changes in the intensity and spreading pattern of land use conflict indices demonstrated the changes in the pattern of territorial space development. Total population, population density, per capita GDP, number of mobile phone users, and road density were strong drivers that influenced the land use conflict of territorial space. Multiple policy recommendations including improving territorial space planning and governance ability, and improving land use efficiency, were proposed to manage and resolve the land use conflict of territorial space. The results and conclusions of this study will help improve future regional land use policies and reduce land use conflict.

“…Current landscapes tend more and more to be human dominated (Kareiva et al 2007;Yang et al 2019), with freshwater biodiversity expected to experience a sharp decline in the future (Sala et al 2000;Pereira et al 2010). Indeed, the density of artificial ponds is increasing at the expense of the density of natural ponds (Oertli 2018), and must be taken into account for J o u r n a l P r e -p r o o f future biodiversity conservation, although they also have to be managed carefully for this purpose (Briggs et al 2019).…”

“…Biodiversity is fundamentally altered by some human activities such as overuse of land, hunting and CO 2 emissions, and these processes have led to a continuous decline in biodiversity (Blowes et al, 2019). To date, the main method used to delay the decline in biodiversity is to establish nature reserves in threatened forest ecosystems (Yang et al, 2019a), but in the future, the red list of ecosystems should be adopted when designating protected areas where biodiversity processes and higher-level components can be maintained (Chen et al, 2020). As the two basic components of biodiversity, species diversity (SD) represents diversity across species, and genetic diversity (GD) represents genotype variation at the intraspecies level and its distribution patterns (Vellend et al, 2014a).…”

Mismatch Between Specific and Genetic Diversity in an Evergreen Broadleaf Forest in Southeast China: A Study Case of 10.24 ha Forest Dynamics Plot of Huangshan

For a long time, forestry management has often focused on the protection of species diversity, and mistakenly believed that protecting species diversity protects genetic diversity. Therefore, research that integrates community ecology and population genetics has become important because it can help elucidate whether the targets for protecting specific and genetic diversity are congruent. In this study, we have emphasized the impact of the community on the population because no previous studies have considered the community composition of a place a priori. Based on the Huangshan 10.24 ha dynamics forest plot, we a priori considered the community composition in the plot to test species-genetic diversity among the tree layers. Firstly, a redundancy analysis (RDA) found that Castanopsis eyrei and Pinus massoniana were the dominant species. Secondly, specific and genetic diversity are not congruent in Huang Shan. Finally, the structural equation model (SEM) showed that the different degrees of response by community composition and population structure to environmental heterogeneity are the main reasons for the mismatch between species diversity and genetic diversity. The results suggest that we must focus on genetic diversity, as well as on protecting species diversity.
