摘要

摘要土地利用/覆被(LULC)的变化对各种环境和社会因素产生显著影响。本文采用多层感知器-马尔可夫链混合模型对金奈市及周边地区至2101年的土地利用价值变化进行了预测。我们还评估了这些变化对地下水补给潜力区(RPZ)的影响，并提出了更好的城市规划政策建议。研究结果表明，建成区面积迅速增加(238 km2/ 10年)，农业用地相应减少(167 km2/ 10年)，水体占用面积持续减少(15 km2/ 10年)。此外，RPZ的估计变化表明高补给潜力地区的减少，强调需要有效的政策来加强地下水补给。该研究为可持续城市发展提供了见解。我们提出了促进绿色城市空间的政策建议，以减轻LULC对地下水补给的影响。感谢印度政府科技部(编号:DST/TM/WTI/WIC/2K17/82(G))的资金支持。我们也感谢印度世界资源研究所提供的土地利用和土地利用变化数据。披露声明作者未报告潜在的利益冲突。作者的贡献le:概念化本研究的思想。PVRS:收集、分析和解释数据。MRK:解释LULC的变化。LK:解释的RPZ变化。所有作者都参与了最终稿件的撰写和审定。数据和材料的可用性本研究中收集、生成和分析的所有数据均可根据伦理准则和资助机构的许可要求提供。作者感谢印度政府科学技术部[编号:DST/TM/WTI/WIC/2K17/82(G)]的资金支持。

Forecasting land use/cover changes and their influence on groundwater recharge in Chennai, India: Recommendations for sustainable urban development

ABSTRACTLand use/cover (LULC) changes significantly impact various environmental and social factors. In this study, we used a hybrid model that integrates Multi-Layer Perceptron-Markov Chain Analysis to forecast changes in LULC of Chennai city and its surrounding area until the year 2101. We also evaluated the impact of these changes on groundwater recharge potential zones (RPZ) and suggested policy recommendations for better urban planning. Our results indicate a rapid increase in built-up areas (238 km2/decade) and a corresponding decrease in agricultural lands (167 km2/decade), with a continuous reduction in the area occupied by the waterbodies (15 km2/decade). Furthermore, the estimated changes in RPZ demonstrate a decline in high recharge potential areas, emphasizing the need for effective policies to enhance groundwater recharge. The study provides insights into sustainable urban development. We recommended policies for promoting green urban spaces to mitigate LULC impacts on groundwater recharge.KEYWORDS: LULCurbanizationweighed overlay analysisrecharge potentialANNMLP-MCA AcknowledgementsWe thank the Department of Science and Technology, Government of India (Grand No: DST/TM/WTI/WIC/2K17/82(G)) for financial support.

期刊介绍： Urban Water Journal provides a forum for the research and professional communities dealing with water systems in the urban environment, directly contributing to the furtherance of sustainable development. Particular emphasis is placed on the analysis of interrelationships and interactions between the individual water systems, urban water bodies and the wider environment. The Journal encourages the adoption of an integrated approach, and system''s thinking to solve the numerous problems associated with sustainable urban water management. Urban Water Journal focuses on the water-related infrastructure in the city: namely potable water supply, treatment and distribution; wastewater collection, treatment and management, and environmental return; storm drainage and urban flood management. Specific topics of interest include: network design, optimisation, management, operation and rehabilitation; novel treatment processes for water and wastewater, resource recovery, treatment plant design and optimisation as well as treatment plants as part of the integrated urban water system; demand management and water efficiency, water recycling and source control; stormwater management, urban flood risk quantification and management; monitoring, utilisation and management of urban water bodies including groundwater; water-sensitive planning and design (including analysis of interactions of the urban water cycle with city planning and green infrastructure); resilience of the urban water system, long term scenarios to manage uncertainty, system stress testing; data needs, smart metering and sensors, advanced data analytics for knowledge discovery, quantification and management of uncertainty, smart technologies for urban water systems; decision-support and informatic tools;...
