Riverine wetland is one of the important cityscapes along rivers, featuring powerful eco-hydrological regulations in safeguarding urban security and serving its quality. Over past several decades, intensified climate change, together with upgraded human activities, have deeply disturbed riverine worldwide caused variations amount pattern, which might lead to negative effects on ecosystem health (WEH), thus threaten sustainability agglomerations. To better understand mechanism above effectiveness, Urban Agglomerations Yellow River China's Ningxia Hui Autonomous Region (RUAN) was taken as an example present study. First, by establishing object-oriented remote sensing image classification system based Classification Regression Tree (CART), distribution years 2000, 2009 2018 were determined for a two-Stage (ST-I: 2000–2009, ST-II: 2009–2018) comparative research. Second, transition matrix landscape index used measure spatiotemporal dynamics two stages. Third, Pressure-State-Response (P-S-R) model, system, constructed comprehensively assess WEH there. Results revealed that: (1) Wetlands RUAN are dominated artificial ones, presenting overall increase area during statistical period, varying different trends Conversion between wetlands non-wetlands found frequent urbanization, leading remarkable changes patterns space. (2) Rivers basic forming RUAN, natural increased period. In general, patches diversity increased, shapes that became homogenized. Accordingly, aggregation decreased fragmentation worsened. (3) most experienced external pressure deterioration state, showing degradation. Meanwhile, more fundamental state itself, disturbance seemed function less. Above findings confirmed vulnerability urbanization arid circumstance. It worthy strengthening protection existing minimizing or eliminating conversion, ensure serve

Evolution of Small and Micro Wetlands and Their Driving Factors in the Yangtze River Delta—A Case Study of Wuxi Area

Remote Sensing, Год журнала: 2023, Номер 15(4), С. 1152 - 1152

Understanding the long-term dynamics and driving factors behind small micro wetlands is critical for their management future sustainability. This study explored impacts of natural anthropogenic on spatiotemporal evolution these areas in Wuxi area using support vector machine (SVM) classification method geographic detector model based Landsat satellite image data from 1985 to 2020. The results revealed that: (1) Natural were prominent area, with an average proportion 70%, although they exhibited a downward trend over last ten years, scale increased 1.5-fold—from 4349.59 hm2 10,841.59 (2) had obvious seasonal variations, most being 0.1–1 1–3 hm2, respectively. From perspective spatial distribution, primarily distributed Yixing district, which accounts 34% area. (3) distribution was systematically affected by human activities. main that annual temperature GDP, interactions between all nonlinear bi-linear. influences weakened, activities steadily emerging as dominant factor distribution. this can provide supportive scientific basis ecological restoration protection wetlands.
