The construction land quota pricing mechanism with cost plus pricing method is not sufficient to reflect its intrinsic value. This diminishes the willingness of farmers to voluntarily reclaim abandoned residential and other rural construction land, leading to suboptimal efficiency in rural land utilization and an excessive squandering of rural land resources. Thus, a sequential auction model with two stages for complementary goods was constructed, which considered the synergic characteristics between the land and quota. Further, regret psychology of bidder was considered in the case of winning or losing. A rational pricing mechanism has been developed to allocate construction land quotas, aiming to enhance farmers' motivation to the vacant homesteads of reclamation and revitalizing the stock of rural construction land. The results revealed that the regret psychology in the case of winning would decrease the transaction price of the quota, i.e., the greater the perceived regret in the case of winning, the more significant the reduction in the bidding price offered. Moreover, the regret psychology in the event of losing/failure would increase the transaction price of quota. Furthermore, publishing only the winner's price after the auction leads to the highest price of the quota offered by the bidder. In contrast, publishing only the loser's bidding price leads to the lowest transaction price of the quota offered by the bidder. In addition, the fee for delayed construction would increase the bidding price of the construction land quota. Therefore, local governments should consider announcing only the winner of price after the quota auction has ended. In addition, imposing a fee for delayed construction would enhance the transaction price of land quota, increase farmers' revenue from land reclamation, and incentivize farmers to reclaim unused rural land.

Influenced by terrain constraints and urban negative externality in mountain valley areas, the suburban village construction lands are not only occupied by cities, but also face hollow-out and decline. Various complex situations of construction land use should be considered in the rural land transfer and planning. In this study, scenario analysis method is used to propose a research framework of "Scenario construction-Benefit evaluation-Dynamic planning".

Understanding how ecosystems respond to ubiquitous microplastic (MP) pollution is crucial for ensuring global food security. Here, we conduct a multiecosystem meta-analysis of 3,286 data points and reveal that MP exposure leads to a global reduction in photosynthesis of 7.05 to 12.

Understanding the morphologies and mechanisms of construction land expansion (CLE) in border areas is beneficial for promoting industrial coordination and cross-border cooperation along the border, also addresses the research gap caused by the predominant focus on construction expansion in economically developed inland cities. This study conducted a comprehensive and systematic comparative exploration of the complex and multidimensional patterns of CLE in the large-scale, multinational sub-regional border areas of the peninsula. Using the Global Artificial Impervious Area (GAIA) dataset, the study innovatively developed a morphology determination model for identifying expansion patterns, integrating morphological characteristic indices.

In the tropics and beyond, roads are key proximate drivers of environmental impacts, including forest fragmentation, fires, mining, and land clearing. Such impacts may be amplified for the initial roads constructed in intact forests-which we term "first-cut roads"-which often promote a rash of associated secondary roads branching off the new infrastructure. These secondary roads in turn can dramatically elevate forest and biodiversity losses.

Groundwater serves as an indispensable resource for freshwater, but its quality has experienced a notable decline over recent decades. Spatial prediction of groundwater quality (GWQ) can effectively assist managers in groundwater remediation, management, and risk control. Based on the traditional intrinsic groundwater vulnerability (IGV) model (DRASTIC) and three vegetation (V) indicators (NDVI, EVI, and kNDVI) and four human activity (H) indicators (land use, GDP, urbanization index, and nighttime light), we constructed four models for GWQ spatial prediction in the Jianghan Plain (JHP), namely DRASTI, DRASTIH, DRASTIV, and DRASTIVH, excluding the conductivity (C) indicator due to its uniformly low values.
