Study on the path of clustering construction of rural primary schools' aesthetic education programs from the perspective of resource integration.

Aesthetic education is an important part of the overall development of students. This study analyzes the number of rural schools and enrollment, number of classes, and number of full-time teachers in those schools from 2013 to 2022, and clarifies the current challenges in aesthetic education in rural elementary schools and the path of quality improvement. It then constructs a curriculum cluster model that shares resources, teachers, management, instructional design, and practical activities, etc.

Changes in soil properties in different land use types in a desert-oasis ecotone, Inner Mongolia, China.

This study aims to examine the changes in soil chemical properties (soil organic matter, SOM; available nitrogen, AN; available phosphorus, AP; available potassium, AK; total nitrogen, TN; total phosphorus, TP and pH) in three depths (i.e. 0-5, 5-10, 10-20 cm) from different land use types of the Green Beach Desert-oasis Ecotone, Inner Mangolia, China.

Spatial distributions of salt-based ions, a case study from the Hunshandake Sandy Land, China.

Soil water soluble base ion salt-based ion concentrations are critical parameters for estimating soil buffer capacity and vegetation productivity. Ionic content clearly covaries with the distribution of plant communities. Previous studies on salt-based ions in soils focused primarily on ion migration and its relationships with vegetation growth.

Using sediment grain size characteristics to assess effectiveness of mechanical sand barriers in reducing erosion.

Wind and sand control features are important tools for limiting desertification. Sand barriers are one of the oldest engineering measures used to reduce wind-sand hazards. Their efficacy and exact mechanism by which they work has remained a topic of scientific debate however.
