Afforestation Partially Offsets Losses of Soil Conservation Services and Carbon Stock From Direct and Indirect Urban Expansion in China

Land Degradation &Development, EarlyView.
ABSTRACT Urban expansion has exerted both direct and indirect impacts on natural land and ecosystem services it supports, driven by increasing population and food demand, yet these underlying pathways remain insufficiently distinguished. Here, we quantified the losses of soil conservation services (water erosion regulation and sandstorm prevention) and

Ecological Network Characteristics of Cultivated Land Carbon Flows in Major Grain‐Producing Regions: Case Study of Jingzhou City, China

Land Degradation &Development, EarlyView.
ABSTRACT Land‐use changes related to cultivated land significantly affect the regional carbon budget in major grain‐producing regions, yet the ecological network characteristics of cultivated land carbon flows remain insufficiently understood. This study developed an integrated framework that combined ecological network analysis with spatial analysis ...

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

Land Degradation &Development, EarlyView.
ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...

Effects of Biochar on Freezing Temperature and Unfrozen Water Content in Pb‐Contaminated Seasonally Frozen Soils: Implications for Mitigating Land Degradation

Land Degradation &Development, EarlyView.
ABSTRACT Freeze–thaw processes are important drivers of land degradation in cold regions, and soil freezing temperature and unfrozen water content are key parameters for characterizing soil hydrothermal conditions and water phase transitions during freezing.

Plant Trait‐ and Soil‐Mediated Responses of Herbaceous Aboveground Biomass Across Community Types Along a Degradation Gradient in the Desert Steppe

Land Degradation &Development, EarlyView.
ABSTRACT Grassland degradation profoundly alters the structure and function of desert steppe ecosystems. However, the responses of herbaceous aboveground biomass (Herb‐AGB) to degradation across different plant community types and the underlying mechanisms remain poorly understood.

Native Perennial Vegetation Buffer Strips Improve Structural Indicators of Riparian Protection in Mediterranean Agroecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Riparian zones in Mediterranean agroecosystems are highly vulnerable to degradation because cultivation often reaches stream edges and annual vegetation senesces during the late‐summer dry period, leaving soils exposed when the first erosive autumn rains occur.

Landslide Hazard Zoning in Bijar Town Using Analytical Hierarchy Method (AHP) [PDF]

نشریه جغرافیا و برنامه‌ریزی, 2015
Landslides and mountainside instabilities are major dangers for human activities which often cause the waste of economic resources and damage to properties and installations. These dangers occur in natural slopes or in slopes changed by man.
