Hills and mountains cover approximately 25 % of Earth's landmass; therefore, investigating landscape ecological risk (LER) in these regions is imperative for ecosystem management. Hilly mountainous susceptible to influences such as desertification erosion include the Southern Hill Mountainous Belt (SHMB) southern China. Over past 30 years, SHMB has undergone significant changes, offering an excellent research case. A comprehensive assessment status this region crucial protection management ecosystems SHMB. This study assessed LER SHMB, identified influencing factors over utilized a patch-generating land-use simulation model (PLUS) project future land use LER. Accounting more than 90 total area, cropland forestland were two most common types From 1990 2020, impervious surface water area saw obvious increases, rising by 154 (from 1209.37 km2 3073.59 km2) 21 1584.78 1924.8 km2), respectively. Grasslands shrublands decreased 54 34 %. It anticipated that there will be little change 2030 compared 2020. Additionally, overall was low, with low- medium–low-risk representing around 70 risk. The general state improved during period but did not converge. Specifically, intensity decrease although showed declining trend. In western portion region, karst displayed increasing LER, severity high-risk increased. Furthermore, natural promote restoration For example, abundance hydrothermal conditions (i.e., increased temperature precipitation) promotes recovery vegetation growth reduces Human activities, construction stations, highways, population, exacerbate contributing increase offers helpful guidance formulating conservation strategies maintain balance sustainability hilly regions.

Considering scale effects in water quality analysis to enhance the precision of influencing factor response analysis

Ecological Indicators, Год журнала: 2024, Номер 163, С. 112091 - 112091

Опубликована: Май 2, 2024

Accurately identifying the optimal spatial scales of effect analysis influencing factors on water quality is crucial for effective environment management. To address this, we propose a framework that consists mix scale division (watersheds, riparian buffers, and circular buffers), conduct case study in Yuanjiang River Basin (YJRB). Scale effects non-linear impacts various were identified. The results revealed variations these indicators predominated by different at sales, such as slope (SL) buffer (w) = 500 m (r) 15 km (with contribution percentage 16.6 %), mean annual temperature (TE) watershed (23.4 precipitation (PR) w r etc. cultivated land (CL) > 28 % (w m, 50 km) will lead to increase total phosphorus (TP) SL 26° pondus hydrogenii (pH). While, POP 30 person per unit area 100 1 km), 24° NDVI 0.48 5 PR 1300 mm watershed, decrease ammonia nitrogen (NH3-N), (TN), electrical conductivity (EC) turbidity (NTU) respectively. Results indicated precision can be improved regulating within considering quality.

Exploring the relationship between land use cover/change (LUCC) and ecosystem service value (ESV) under different future scenarios can provide guidance for selecting development patterns scientific utilization of resources in region. In this study, LUCC North Slope Tianshan Mountain (NSTM) was simulated using PLUS model. The ESV coefficients were adjusted regional differences social factors to better reflect actual situation study area. interactions LUCC, landscape pattern (LSP), systematically analyzed, while at same time, level economic fitted Ecological Kuznets Curve, which then used determine its trend inflection point. following conclusions drawn: (1) Cropland unused are main types change NSTM, both historically future. shows an increase natural scenario a decrease ecological protection scenario. Unused scenarios, indicating that has higher potential NSTM. NSTM continuous (2) LSP historical have evolved show fragmentation, heterogeneity, complexity patch forms. However, is slower than LSP, form integrated framework interactions, where influences through changes feedback acts as bridging mediator. (3) Curve exhibits N-shape, showing clear overall rightward across annual level. At interannual level, curves situated middle declining phase with no point occurring during period. contrast, display declining-ascending trend, when per capita GDP reaches 2.5 × 10^6 CNY.
