Under the background of global climate change, characterizing correlations between vegetation dynamics and bioclimatic indices (calculations based on temperature, precipitation, reference evapotranspiration) are important for conservation restoration fragile ecosystems. The Southwest China (SWC), which is a hotspot biodiversity with complex diverse terrain, stereoscopic climatic characteristics, pronounced spatial heterogeneity. Here, spatial–temporal changes in factors annual normalized...

A precise multi-scenario prediction of future population, based on micro-scale census data and localized interpretation global scenarios, is significant for understanding long-term demographic changes. However, the used in previous research need to be further refined. Few studies have focused predicting sex ratio at birth, which vitally important estimating size structure population. It also interpret set parameters China’s population development line with framework shared socioeconomic...

National Sustainable Development Agenda Innovation Demonstration Zone in Lincang City, Southwest China Revealing the current water quality status rivers and reservoirs its drivers is crucial to achieving United Nations Goal 6 (SDG 6). We assessed spatial-temporal dynamics influence of natural socioeconomic factors on index (WQI) parameters using redundancy analysis (RDA) partial least squares path model (PLSPM). The results indicate following. (1) annual average values WQI City from 2018...

The ecosystem services (ESs) and landscape patterns (LPs) in a region have marked impact on human production life even play an important role the achievement of regional Sustainable Development Goals (SDGs). Given limited consideration LPs ESs SDGs current research, it is especially crucial to provide comprehensive targeted policy support for sustainable development less developed areas from environmental perspective. Utilizing Lincang National Innovation Demonstration Zone as case study, we...

The high-quality development in the Yunnan–Guizhou region (YGR) is a significant support for of China. It will help shape new pattern regional coordinated development. Referring to Beautiful China and United Nations Sustainable Development Goals (SDGs) evaluation indexes, we built an index system that puts at its heart. This includes resource load, economic development, ecological environment protection, social progress. Taking 25 prefecture-level cities YGR as study subjects, authors used...

Understanding the evolution and propagation of different drought types is crucial to reduce hazards in arid semiarid regions. Here, Standardized Precipitation Index (SPI), Streamflow Drought (SDI), Vegetation Condition (VCI) were used investigate spatiotemporal variation correlations between Pre (Pre-R)/post (Pos-R)-reservoir. Results showed that average peak/intensity/duration/severity meteorological droughts (MD) greater Pre-R than Pos-R period upstream Heihe River Basin (UHRB), while...

This study aims to assess the current status of green agricultural development and its influencing factors in Lincang City, a national innovation demonstration zone for sustainable development; it also seeks enhance potential competitiveness underdeveloped border areas. To achieve this, an evaluation index system is constructed encompassing six dimensions. Using coupled coordination obstacle degree approach, this explores spatiotemporal differences level development, as well power, degree,...

Water-saving irrigation behavior (WSIB) is important for sustainable economic and social development in river basins promoted by improving water-saving awareness. Understanding the factors of WSIB could facilitate water demand management information campaigns. Using theory planned behavior, this paper analyzes influence subjective attitude, perceived behavioral control norms on intention final with a structural equation model (SEM). Moreover, comparative study upper, middle lower reaches...

Guizhou Province, China, experienced several severe drought events over the period from 1960 to 2013, causing great economic loss and intractable conflicts water. In this study, spatial temporal characteristics of droughts are analyzed with standard precipitation index (SPI), comprehensive meteorological (CI), reconnaissance (RDI). Meanwhile, historical records used test performance each at identifying droughts. All three indices show decreasing annual autumn trends, latter particularly...

Southwest China (SWC) is a critical hotspot of biodiversity and highly sensitive to climate change. To better protect biodiversity, many National Nature Reserves have been established maintain viable populations species minimize their habitat loss. However, the response normalized difference vegetation index (NDVI) in extreme events has not described. We analyzed NDVI changes made several key observations: (1) from 1998 2019, annual average trends 0.00421 yr−1, 0.00514 0.00529 yr−1 were...

Abstract Extreme persistent precipitation is becoming increasingly common globally, and extreme regional events (PERPEs) pose a particularly serious threat to humans environmental systems. This study investigated total (TP), daytime (DP), night‐time (NP) in southwest China (SWC) during 1961–2019. The occurrence of TP, DP, NP was analysed under the conditions persistence over 1–5 days, temporal >2 nonpersistence ≤2 spatiotemporal overlap for at least 3 days (i.e., PERPE) using objective...

Fewer studies on ecological security (ES) in border areas limit the synergistic development of context rapid globalization. The study ES southwest China can enrich evaluation methods, summarize knowledge related to areas, and provide references for similar world. Therefore, twenty-five international counties Yunnan Province were selected establish a system evaluate ES; an entropy weight TOPSIS model was used changes from 2004 2019. Then, obstacle degree diagnose factors affecting ES. state...

Changes in precipitation are critical indicators of climate change. In this study, the daily records from 10 meteorological stations Heihe River Basin, Northwest China 1961–2016, indices, and normalized differential vegetation index (NDVI) were investigated using Pearson, Kendall, Spearman correlation coefficients; Theil-Sen Median; Mann–Kendall test; wavelet coherence. The results indicated that occurrences (fractional contributions) 1–2-day wet periods 81.3% (93.9%) 55.3% (82.1%) upper...

Technological changes in water use efficiency directly influence regional sustainable development. However, few studies have attempted to predict because of the complex influencing factors and diversity. The Chinese Government has established a target 0.6 for effective utilization coefficient irrigation water, but it is not clear how will change different provinces future. purpose this study using conditional convergence model combined with shared socioeconomic pathways (SSPs) scenario...
