Introduction Extreme environments such as prolonged high temperatures and droughts can cause vulnerability of vegetation ecosystems. The dry-hot valleys Southwestern China, known for their extremely annual temperature, lack water, unique non-zonal “hot island” habitat in the global temperate zone, provide exceptional sites studying how plant adapts to dry hot environment. However, specific local biotic-environment relationships these regions remain incompletely elucidated. study aims evaluate valley-type Savanna species communities adapt long-term drought high-temperature stress environments. Methods investigated changes diversity communities’ aboveground biomass a along an elevation gradient Yuanmou valley Jinsha River basin, southwest China. Subsequently, general linear model was utilized simulate distribution pattern diversities constituent gradient. Finally, RDA VPH mothed were used impacts contributions environmental factors or variables on patterns. Results discussion field survey reveals altitudinal effect Savanna, with dominant shrubs herbs plants below 1700m, significant positive relationship between SR , Shannon-Wiener Simpson Pielou indices altitudes. Relatively, community did not increase significantly elevation, which mainly due decreased herbaceous elevation. Different regulators shrub-herbaceous functional groups made different patterns Savannas.

Protected areas (PAs) play a key role in mitigating ecological crises. Currently, priority protected (PPAs) focus on biological conservation, and few studies have considered the connectivity between patches. Few formulated future conservation measures from two dimensions of security pattern (ESP) reserve effectiveness. To fill this gap, study use ESP to identify that meet objectives. We take Wuhan metropolitan area as research area. constructed framework for formulating development plans based areas. The complete method system, we focused construction evaluation index system landscape connectivity. Then, effectiveness PAs could be evaluated, PPAs identified. results showed there were five isolated among existing PAs. Moreover, total was 9328.91 km2, they had high value. Due low protection rate PPAs, are not main target PAs; thus, new According our plan, with different classes will achieve functions work. Our focuses achieving sustainable formulates environmental land planning balance urban development. It can provide information support realization 2030 vision

The Qinghai–Tibetan Plateau (QTP) is one of the most vulnerable ecosystems worldwide. Over last few decades, QTP has been subjected to increasing external pressures, such as climate change, human activity, and natural hazards. Therefore, ecological risk assessment vital for environmental protection sustainable development QTP. A landscape (LER) based on disturbance vulnerability was performed explore spatiotemporal characteristics associated with LER in from 1990 2020. Furthermore, impact quantitatively evaluated a boosted regression tree model. Results showed that more than 70% locations exhibited below-medium LER. demonstrated downward trends presented during periods 2001 2012 2020 no significant trend period 2002 2011. Additionally, high-LER areas were concentrated northwestern QTP, whereas low-LER mainly southeastern displayed clustering across Changes climate, topographic distribution, activity influenced stability study area. Precipitation temperature had strongest effects LER, followed by elevation grazing intensity. Lower precipitation temperatures higher Our results provide precise specific support management other ecologically fragile areas.

Identifying the spatial heterogeneity characteristics of ecosystem services (ESs) and their influencing mechanisms is crucial for regional ecological management sustainable development. This study quantified net primary production (NPP), water yield (WY), soil conservation (SC), sand fixation (SF), habitat quality (HQ) total service (TES) on Qinghai Tibet Plateau (QTP), then analyzed spatial–temporal ESs. The geographical detector model (GDM), geographically weighted regression (GWR) model, constraint lines were used to explore effects factors results showed that (1) NPP, WY, SC, HQ TES an increasing trend from 2000 2018, while SF a decreasing trend. SC distribution pattern "high values in southeast low northwest", high located northern QTP southern QTP. (2) NDVI was key factor TES, precipitation dominated mainly influenced by Largest patch index (LPI). (3) In most areas, natural (precipitation, temperature, DEM, slope NDVI) had positive both negative HQ. human (Resident, Road LPI) other There non-monotonic Overall, much stronger influence ESs than factors, interactions among independent effects. this can provide basis protection
