DIGITAL EXTRACTION AND CHANGE ANALYSIS OF ALTITUDINAL NATURAL ZONES IN TIANSHAN TOMUR NATURAL HERITAGE SITE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 The Tomur Natural Heritage Site possesses the most typical altitudinal natural zones on the south slope of the Tianshan Mountains. Five altitudinal zones have developed on the south faced slope, including: warm temperate desert zone, mountain steppe zone,

Major Type of Mattic-Epipedon Ruptures in Alpine Meadow Ecosystems on the Qinghai–Tibet Plateau
Ecosystem Health and Sustainability, 2023 Alpine meadow degradation is an important issue for ecosystem stability in the Qinghai–Tibet Plateau (QTP). As an essential part of alpine meadow ecosystems, mattic epipedon (ME) refers to the soil surface horizons rich in organic matter and roots, which

Northwest Science, 2013 Abstract The importance of climate warming on forests is recognized worldwide and has increased attention on the significance of both timberline advance and alpine meadow invasion by forests. Successful seedling regeneration in alpine meadows depends on availability of suitable substrates, or microsites, for seedling establishment.

Quantifying the Controls on Evapotranspiration Partitioning in the Highest Alpine Meadow Ecosystem [PDF]
Water Resources Research, 2020 AbstractQuantifying the transpiration fraction of evapotranspiration (T/ET) is crucial for understanding plant functionality in ecosystem water cycles, land‐atmosphere interactions, and the global water budget. However, the controls and mechanisms underlying the temporal change of T/ET remain poorly understood in arid and semiarid areas, especially for

The Great Caucasus alpine belt syntaxonomy. Alpine meadows with restricted distribution
Vegetation of Russia, 2001 Alpine meadows with prevalence of perennial herbs and grasses and alpine fruticose-lichen heaths are widespread within the Great Caucasus alpine belt, 2400—3200 m above the sea level. The association Hedysaro hedysaroidis—Campanuletum collinae is met in the Western and Central Caucasus.

Spatiotemporal Coupling Relationship Between Plateau Pika Disturbance and Alpine Meadow Degradation
Shuitu baochi tongbao, 2023 [Objective] Plateau pika (Ochotona curzoniae) is a key species in the alpine meadow ecosystem of the Qinghai-Xizang Plateau. The coupling relationship between pika activity and meadow degradation was analyzed in order to further improve the observation ...
