[Quantifying the Carbon Reduction Difference Based on Households' Willingness to Transform Their Lifestyles from the Micro Perspective].

Cities are gathering places for residents, industries, and energy consumption, and the carbon emissions generated by urban residents' consumption are becoming increasingly prominent. Under the "dual carbon" goal, how to effectively guide the transformation of urban households' lifestyles and achieve consumption side carbon reduction has become an important issue. Based on questionnaire surveys and face-to-face interviews in the main districts of Hangzhou, the total amount and component of household consumption carbon reduction potential in Hangzhou were calculated by adopting a carbon emission coefficient model, and the relevant factors influencing various types of household consumption behaviors and carbon reduction potential were analyzed through virtual regression models and binary logistic regression.

Micro-agents' perception of landscape services and their multi-level driving influences in the headwater area of the Qiantang River, China.

Landscape services are an important basis for maintaining regional ecological security patterns, environmental health, and sustainable socio-economic development. As an important link between regional ecosystems and socio-economic development, micro-agents' production and life as well as their cognition and perception of landscape services notably impact the maintenance of multi-functional landscape development. This paper examines 9 rural communities in different areas and different development types in the headwater area of the Qiantang River in China, China's national key ecological functional area, in a typical case study.

[Distribution Characteristics, Ecological Risks, and Source Identification of Heavy Metals in Cultivated Land Under Non-grain Production].

The purpose of this study was to explore the distribution characteristics and potential ecological risks of soil heavy metal pollution of cultivated land under non-grain production. Taking a typical area around Hangzhou Bay as an example, 254 topsoil samples (0-20 cm) of cultivated land were collected, and the content of eight soil heavy metals in four different cultivated land use types, including grain, seedlings, vegetables, and fruits, was analyzed. The ecological risk was assessed by the Nemerow pollution index and the potential ecological risk index, and the PMF model was used to identify the source of soil heavy metals in the study area.

Multi-functional identification of social-ecological landscape in ecologically fragile areas under the background of regional transformation development.

To realize the coordinated development of regional economy, society, and ecosystem is the ultimate goal of economic development and ecological protection in ecologically fragile areas. The multi-functional identification of socio-ecological landscape in ecologically fragile areas is helpful to alleviate the practical contradictions and conflicts faced by the region, and to better realize the optimal allocation of regional resources and the formulation of rational regional land management and planning strategies. This study takes Mizhi County, the most prominent and representative area of the ecologically fragile areas of the Loess Plateau, as the research area.

Trade-offs between economic benefits and environmental impacts of vegetable greenhouses expansion in East China.

Greenhouse vegetable cultivation (GVC) has become a global issue in agricultural land use in recent years. While the use of GVC brings considerable economic profits, it has significant environmental impacts, with a risk of threat to sustainability. To make sound development and management strategies, it is necessary to characterize the trade-offs between the benefits and costs of GVC expansion.

Integrated analysis of urbanization-triggered land use change trajectory and implications for ecological land management: A case study in Fuyang, China.

Land use change under rapid urbanization can drastically change terrestrial ecological conditions. This study presents an integrated analysis of land use dynamics and the resultant ecological impacts on sustainable development over the past 25 years (1990-2015) in response to urban development. Remote sensing and geographic information system techniques were employed to examine the spatiotemporal trajectory of land use changes.

Spatiotemporal Variability of Soil Nitrogen in Relation to Environmental Factors in a Low Hilly Region of Southeastern China.

Soil total nitrogen (TN) plays a major role in agriculture, geochemical cycles and terrestrial ecosystem functions. Knowledge regarding the TN distribution is crucial for the sustainable use of soil resources. This paper therefore aims to characterize the spatiotemporal distribution of soil TN and improve the current understanding of how various factors influence changes in TN.

A Comparative Assessment of the Influences of Human Impacts on Soil Cd Concentrations Based on Stepwise Linear Regression, Classification and Regression Tree, and Random Forest Models.

Soil cadmium (Cd) contamination has attracted a great deal of attention because of its detrimental effects on animals and humans. This study aimed to develop and compare the performances of stepwise linear regression (SLR), classification and regression tree (CART) and random forest (RF) models in the prediction and mapping of the spatial distribution of soil Cd and to identify likely sources of Cd accumulation in Fuyang County, eastern China. Soil Cd data from 276 topsoil (0-20 cm) samples were collected and randomly divided into calibration (222 samples) and validation datasets (54 samples).
