The present study investigated LULC Jajrud Area (JPA) Kavdeh Wildlife Refuge (KWR) Tehran province, Iran, between 1989 2019. To inform ecological measures JPA KWR, were identified monitored using Landsat imagery from In addition, landscape risk (ER) was evaluated by conducting pattern index analysis.

Social-economic development and urbanization greatly modify landscape patterns their associated ecological processes at regional scales, resulting in serious risk (LER). Effectively evaluating the LER is basis for sustainable land use of regions. Because uncertainties future socioeconomic development, precisely projecting distribution still challenging. To overcome this weakness, by using Fujian Delta region as a case study, we employed patch-generating simulation (PLUS) model coupled with multiple linear regression Markov chain to project 2050. The Shared Socioeconomic Pathways (SSPs) proposed Intergovernmental Panel on Climate Change (IPCC) were selected scenario framework. Thus, spatiotemporal characteristics pattern changes from 2000 2020 projections 2050 under different localized SSPs scenarios explored. results show that cropland water areas changed remarkably during 2000–2020. PLUS based couple has higher prediction accuracy (FoM = 0.244) than without 0.146). urban continued expand westward northward Large amounts will be transformed into eastern part. conversion area largest SSP2 scenario, smallest occurs SSP4 scenario. From 2020, exhibited an east–west polarized spatial distribution, gradually increased. projected have LER, SSP1 conversions lead most significant increases followed grassland land.

Landscape ecological risk reflects the extent to which ecosystems are threatened by human activities and environmental changes is increasingly seen as basis for decision-making in regional ecosystem management. Although Yangtze River Economic Belt (YREB) has experienced drastic land use affected activities, spatiotemporal heterogeneity of region not been thoroughly investigated. This study develops applies an assessment framework that integrates landscape pattern characteristics vulnerability dynamics analyze variations YREB from 2000 2018. The results show moderate levels across most during period, but was notably higher western northern regions. Due gradual improvement policies implementation restoration projects, there a clear trend reduction, area previously designated high or medium–high reduced more than 150,000 km2 over period. Approximately 45% area, where risks difficult mitigate maintain at lower levels, identified key future Significant differences underscore necessity implementing spatially differentiated management strategies long-term dynamic monitoring. provides reference optimization sustainable YREB.

Exploring the spatial–temporal heterogeneity of landscape fragmentation contributes to realizing dynamic evolution pattern and understanding impacts physical-geographical environment human activities on systems. Differing from previous studies that focused using single metrics characterize fragmentation, this study proposed a Landscape Fragmentation Index (LFI) assess analyze China's in 1980–2020. The result showed characterizing patch size, shape, density, type, cluster, distance were equipped with obvious phased change characteristics, all them have successively undergone stable phase, fluctuation adjustment phase. In 1980–2020, LFI was gradually increased 0.393 0.383, annually rising by 0.07 percent points average. Also, annual average growth urbanization rate GDP respectively reached 1 point 9.26 points. Besides, regarding spatial pattern, relatively features Southwest-Northeast (Hu Line) Northwest-Southeast (Bole-Taipei directions Hu Line manifested as dividing line while Bole-Taipei shown equilibrium line.

Multi-source ecological risks have induced many pollution problems that cannot be ignored and seriously threaten regional security. Constructing optimizing the landscape pattern is beneficial to improve watershed ecosystem services. In this study, an innovative method proposed construct optimize pattern, which takes Luojiang-Small Creek as example. 10-meter high-precision raster elements are selected basic unit for risk evaluation, 20 evaluation factors from three dimensions of "natural environment-human society-landscape pattern" establish index system. The spatial principal component-redundancy analysis (SPCA-RDA) was used comprehensively evaluate in 2019, minimum cumulative resistance model (MCR) gravity were watershed. results show (1) Human social a more significant influence on integrated risk, while natural factors, except soil type vegetation cover, weaker risk. (2) overall low, area mild zone 259.89 km2, accounting 81.68 % study area. According MCR model, forest land with larger than 1 km2 water bodies grassland 0.01 identified source sites.

As critical prerequisite for sustainable development research of social ecosystem (SDSE), the relationship between landscape security pattern and services should be explicitly evaluated to support SDSE research. However, existing evaluation system lacking integrating analysts factors led vague knowledge mechanism. To tackle this issue, study, therefore, explored ecological risk (e.g. carbon sequestration, soil conservation, water yield, crop production residential support) at Xi'an Metropolitan Area using remote sensing data in 2010 2020. The results show that overall decreased from 0.2618 0.2479. Although rapid urban leading improvement support, total has declined due decline yield production. Preventing on fragmentation cannot improve level services. Notably, stronger interference human activities overwhelmingly caused a single advantageous with extreme risk, while less multiple regulation medium–low risk. Additionally, competitive would not produce higher by intervention activity. sequestration (or conservation) resulted high Using these results, potential spatial plan is then made based areas This study benefits decision-making regional comprehensive prevention, future planning orientation, ecosystem.
