Spatiotemporal Interactions of Land Use Change, Land Surface Temperature, and Vegetation Dynamics in China's Caohai National Nature Reserve

Land Degradation &Development, EarlyView.
ABSTRACT Understanding the spatiotemporal dynamics of land use change (LUC), land surface temperature (LST), and vegetation indices is critical for assessing ecological changes and informing sustainable land management. This study investigates the long‐term interrelationships between LUC, LST, and vegetation indices in China's Caohai National Nature ...

ارزیابی تأثیر روش‌های هموارسازی بر محاسبۀ فنولوژی در جنگل‌های زاگرس با استفاده از داده‌های ماهوارۀ مودیس (مطالعۀ موردی: مریوان) [PDF]

مجله جنگل ایران
مقدمه: تغییر اقلیم به تغییرات عوامل آب‌و‌هوایی یک منطقه در دورۀ بلندمدت اطلاق می‌شود و تأثیر مهمی بر فرایندهای اکولوژیکی آن منطقه دارد. بررسی تغییرات فنولوژی گیاهان، اهمیت زیادی در درک رفتار اکوسیستم‌های زمین در مواجهه با تغییرات اقلیمی دارد.

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

Land Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Paddy Field Mapping Using Multi-Source Remote Sensing and Random Forest in a Small-Scale Area of Tegallalang, Bali [PDF]

E3S Web of Conferences
Paddy field mapping is essential to distinguish paddy fields from other vegetation or other cropland. However, mapping in long term faces challenges because of short lifespan of the plants causes land to change rapidly from one phase to another.

Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute
