The Qinghai–Tibetan Plateau (QTP) has the largest area of natural grassland in China, and continuous degradation poses a serious threat to regional ecological security sustainable resource management. It is essential comprehensively evaluate cost–benefit differences drivers across various zones enhance management practices. This study presents zonal framework for restoration degraded grasslands based on analysis, specifically applied Qinghai Northeastern QTP. results indicate: (1) Although overall NDVI shows an upward trend, some areas still exhibit significant degradation. (2) Cost–benefit analysis can divide into four types Ecological Management Zones (EMZs): high-cost–high-benefit zone, high-cost–low-benefit low-cost–low-benefit low-cost–high-benefit zone. (3) driving factors show different EMZs. Based these research findings, differentiated spatial planning strategies were developed each EMZ. not only provides scientific methodology but also offers important insights resources QTP other ecologically sensitive areas.

Ecosystem surface plays an important role in maintaining ecological balance and supporting economic development. Accurate effective identification of ecosystem with different uses allows for better categorization management contributes to the orderly restoration ecosystems. In this study, Human Footprint Index (HFI) is constructed by comprehensively considering factors biodiversity, human activity impacts, geometric features, combined multi-factor knowledge constraints such as changes land cover. We carry out accurate analysis surfaces, using Changzhou City's tree cover a test area. The results show that: (1) degree affected activities City varies greatly, Gross Domestic Product (GDP) elevation are main affecting level HFI. (2) distribution native artificial uneven, more than 95% surfaces distributed peripheral areas city higher elevations farther away from center. Artificial likely be found high GDP frequent activities, mainly urban centers large proportion buildings along roads. (3) overall accuracy 83.20%, which center area slightly lower agricultural production land. study provide method objective, surface, can improve enthusiasm local governments fulfilling their protection duties contribute efficient achievement goal civilization construction.

Biological invasion poses a critical global issue, leading to substantial detrimental impacts on biodiversity, the environment, and economy. The objective of study is offer thorough understanding how both climatic human-induced elements impact geographic richness invasive plant species across Loess Plateau. We evaluate distribution at county level Plateau by examining herbarium records from China. incorporate 16 anthropogenic variables depict local environmental settings. Furthermore, we apply classification regression tree approach investigate correlation between identified factors. Our demonstrates that total 401 are identified, which spread 249 genera 61 families. Among these, Asteraceae family stands out as most prevalent, trailed Poaceae Fabaceae. spatial reveals notable trend, with highest frequencies found in southeastern parts region lowest northwestern areas. It noteworthy regions higher levels economic advancement tend harbor more significant abundance species. predominantly shaped combination human variables, such annual precipitation, gross domestic product, maximum temperature warmest month, minimum coldest month. To fully comprehend ecological biological mechanisms underlying diversity Plateau, pioneering conceptual framework has been established. suggests achieving harmonious equilibrium among development, conservation, mitigation essential for recognizing emerging risks associated habitat alterations, climate change, socio-economic advancements arid regions.

Globally, natural habitats have suffered tremendous damage from human activities, a phenomenon that is increasingly evident in basin regions. The management of regions dependent on understanding the various impacts activities these ecosystems. Despite studies been conducted effects regions, there still lot doubt regarding impact quality To fill this gap, study employs series spatial analysis methods and logistic regression modeling to delve into temporal patterns habitat Yangtze River Basin (YRB) as well differences sub-basins YRB. findings indicate 0.408% decline overall environmental YRB area 2000 2020, accompanied by 15.396% surge activities. Notably, southeastern Qilian Mountains mountainous northwestern sector Sichuan emerge pivotal areas for restoration. Conversely, southwestern urban clusters Delta (YRD) face significant deterioration. Spatial analyses reveal noteworthy trend: burgeoning region pose substantial threat recovery efforts. Further differential focusing upper, middle, lower segments underscore exert most pronounced within region, while upper experiences least influence. implications are manifold.
