Understanding the dynamics of vegetation responses to climate change can provide important information for environmental management. The Qilian Mountain Nature Reserve in Northwest China, a high-altitude mountainous region that is critical ecological importance, has been affected by drastic change. However, response this area not established. This study aims address three unanswered questions. First, what relative importance temperature and precipitation driving regional change? Second, how...

Balancing the relationship between rural development and protection of water resources is a challenging undertaking. This study develops coupling coordination degree (CCD) model to examine non-linear interaction environment in 11 prefectures Gansu, northwestern China. There are three key findings. First, economic driver development, whereas social has relatively little impact. For subsystem, improved efficiency been contributor, environmental carrying capacity secondary. Second, CCD...

Abstract This study proposes a random forest algorithm to evaluate water poverty. It shows how the machine learning technique can be used classify degree of poverty into five levels: very severe, moderate, mild, and mild. The strengths proposed method include high classification accuracy, good operational efficiency, ability handle high-dimensional datasets. success is empirically illustrated through case in Gansu, Northwest China. analysis that from 2000 2017, severity area declined. In...

Drought is one of the major climate disasters leading to forest degradation in dryland mountains. Hence, revealing response resilience drought crucial predict succession mountains under future global warming. Here, we chose Qilian Mountains as study area and calculated recovery time intensity along elevation from 1982 2020 using Leaf Area Index (LAI) Standardized Precipitation Evapotranspiration (SPEI). Then, was an exponentially fitted curve between corresponding time. Finally, dominant...

Vegetation responses to climate change are typically nonlinear with varied time effects, yet current research lacks comprehensiveness and precise definitions, hindering a deeper understanding of the underlying mechanisms. This study used mountain-type Qilian Mountains National Park (QMNP) in China as case systematically investigate characteristics patterns these effects using generalized additive model (GAM) based on MODIS-NDVI, seasonal temperature, precipitation data. The results show that...

Fragile dryland ecosystems are at increased risk of destabilization with the frequent occurrence hydro-meteorological anomalies. Recent studies assessing ecosystem stability have primarily considered precipitation (PRE) and often neglected response to soil moisture (SM) potential evapotranspiration (PET). Meanwhile, mechanisms that influence spatial variability require further investigation. Based on Normalized Difference Vegetation Index (NDVI) from 2001 2022 responses changes in PRE, SM...

Abstract 明清易代之际, 满汉文化易位、政治权力换手以及士大夫个人命运的转折将传统 的变革推到了个人和群体面前。在所有这些冲突中, 满族统治阶层、汉族理学官僚、 汉族遗民士人对于各自传统的捡拾、遗弃、变换及其决断无可置疑地居于核心地位。 在激烈的政治文化之外, 以理学为代表的儒学, 采取既不批判现实也不反传统的政治 立场, 通过讲理 (讲理学) 与清政权碰触、试探, 确立了新传统; 以康熙为首的清政 权与理学官僚展开了互动, 确立了儒学化的新文化传统; 在亲眼目睹了清政权的文化 选择后, 晚明遗民的政治心态发生了转变, 放弃了其传统观。这些对于传统的抉择, 其特殊时期的视角和激烈的程度以及并非诉诸武力的方式, 颠覆了我们对于中国传统 的种种约定俗成的结论。 关键词: 理学 康熙 儒学化 遗民 During the dynastic change from Ming to Qing, Manchu and Han cultures also changed places. The transfer of political power in fortunes...

Ethics based on Confucian moral virtues and guides as core values have long formed the “old tradition” in determining direction of China’s social development. Changes urban residents’ corresponding changes life styles late Ming Dynasty demonstrated emergence a new cultural tradition that advocated for human freedom development individuality, material enjoyment pleasures life, questioned critiqued guides. Although such had not yet matured, its humanist made deep imprints period. This survived...

Green development is an important way to achieve global sustainable goals, and has become one of the main research hotspots in recent years. Balancing economic environmental protection turned out be a great challenge Beijing, capital China, which can provide some suggestions on ecological civilization construction green for other cities. However, there have been limited studies this crucial topic. Therefore, based statistical data Beijing from 2006 2016, paper constructed evaluation system...

This study for Muslim migrants with three attributes (minority, religious belief). The purpose to reveal commonalities differences living spaces Migrants multi-ethnic cities Lanzhou Xi’an, provide guidance targeted management promote their integration. Based on available research data from 2017-2019, adopts spatial analysis regression explore results...

Abstract The deep, tight gas reservoir in the Daqing oil field, P. R. China has multiple parallel sandy conglomerates with horizontal heterogeneity and poor historical production from vertical wells single-lateral wells. These blocks comprise a large volcanic reservoir, which is also challenging for directional drilling. This paper describes dual-lateral completion hydraulic fracturing that addresses these issues. To deploy stacked well this deep depth its high temperature are considered....

Abstract Drought is the major climate disaster experienced by dryland mountains. However, altitudinal differentiation of forest resilience to drought and its dominant factors in mountains largely unknown, which crucial predict whether primary forests will collapse under future global warming. In this study, we selected leaf area index (LAI) standardized precipitation evapotranspiration (SPEI), fitted curves based on intensity recovery time, calculated curve define along elevation zones...
