中文摘要:
      华北平原地下水的大面积超采,导致该地区发生湿地退化的生态环境地质灾害。以保定市为研究区,基于2000、2005、2010、2015、2020年的土地利用数据,利用GIS技术对研究区的湿地分布与变化情况进行分析,探明研究区部分区域存在湿地退化现象,进一步采用Python语言构建马尔科夫模型,分别模拟自然演化情景、超采加剧情景、自然补给情景下2025年研究区湿地的演变趋势,并根据演变趋势进行相应预测分析。结果表明:2000—2010年研究区湿地总面积呈现减少趋势,湿地退化现象严重;2010—2020年湿地总面积开始增加,研究区的湿地退化现象得以缓解。与2020年相比,2025年研究区自然演化情景下湿地面积增加16.23 km2,但在安新县、阜平县、曲阳县和唐县的退化现象仍较为严重;超采加剧情景下湿地面积减少13.94 km2,开采点周围区域发生显著的湿地退化现象;自然补给情景下湿地面积将随着降雨等级的提高分别增加21.68、27.32、32.82 km2,湿地退化现象的缓解程度也随之不断增强。本研究结果对湿地保护与管理以及地下水超采的治理管控具有重要的指导意义。
英文摘要:
      Groundwater overexploitation in North China Plain have intensified wetland degradation. To identify the degradation situation in Baoding City, we analyzed the distribution and changes of wetlands using GIS technology based on the land use data of 2000, 2005, 2010, 2015, and 2020. Additionally, a Markov model was constructed by Python to simulate the wetland evolution in the study area in 2025, under the scenarios of natural evolution, intensified groundwater overexploitation and natural recharge. Prediction analysis was duly conducted based on the simulated evolution trends. The results suggest that the total area of wetlands showed a decreasing trend from 2000 to 2010, indicating a severe wetland degradation in the study area. Then, it began to increase from 2010 to 2020, suggesting a mitigation of wetland degradation. By 2025, the wetland area in the study area is projected to increase by 16.23 km2 under the scenario of natural evolution; however, the degradation remains severe in Anxin County, Fuping County, Quyang County, and Tang County. Under the scenario of intensified groundwater overexploitation, the wetland area is expected to decrease by 13.94 km2, with significant wetland degradation distributing in the periphery of extraction sites. Conversely, under the scenario of natural recharge, the wetland area will increase by 21.68, 27.32, and 32.82 km2, corresponding to the rising levels of precipitation, which will in turn lead to a continuous improvement in the degradation. The research results can provide a technical support for wetland protection, as well as the management and control of groundwater overexploitation.
