摘要
【目的】农业景观是区域内自然环境和生产活动的客观呈现,具有地域性和多样性,在快速城市化背景下,评估农业景观特征可为农业景观管理及保护提供重要基础。【方法】应用景观特征评估(landscape character assessment,LCA)对珠江三角洲冲积区农业景观进行景观特征分类,选择地理演变分区、土地覆盖类型、土地利用现状等作为特征叠加要素。【结果】通过GIS分析和人工辅助修正,划分出6类一级、14类二级农业景观特征类型,并绘制出区域尺度的农业景观特征地图;同时对特征类型进行了属性归纳和类型学分类,总结出3类农业景观:基塘农业景观、田园农业景观、花卉苗木农业景观,并进行典型样本(5 km×5 km)图解与特征描述。【结论】明确了堤围及堤围所划分的水系结构和土地边界是该地区农业景观的关键特征,并针对不同类型的农业景观,分别提出保护、更新、维持的管理策略。
[Objective]The agricultural landscape in the alluvial plain of the Pearl River Delta is spread over the plains formed by the alluvial deposits of many rivers in the shallow bay.The highly developed river network and water system,while providing convenience for agricultural production,also place higher demands on the rational development of soil and water resources.In history,local residents mainly adopted the method of embankment construction and reclamation to compete with the rivers for fields,and the interaction between humans and water lasted for more than a thousand years,giving birth to an agricultural landscape with unique landscape characters.Agricultural practices have led to profound landscape changes,with corresponding landscape characters being the result of the interaction between natural and human factors.However,in the practice of rapid urbanization and agricultural intensification,homogenized and standardized construction is rapidly expanding,and modern urban landscape elements are superimposed on traditional agricultural landscape,making the landscape highly fragmented with their characters weakened or deviating from the original landscape characters,while resulting in a continuous loss of the diversity and continuity of the agricultural landscape.Character assessment is an important basis for the management and conservation of the agricultural landscape in the context of rapid urbanization.[Methods]This research adopts the landscape character assessment(LCA)method to categorize the characters of agricultural landscape in the alluvial zone of the Pearl River Delta,and selects geographic evolution,river basin,and land cover as character superimposition elements.To better represent the interaction between natural processes and human activities or the degree of interaction between the two in the past,and to understand the historical influence if such interaction on landscape formation and characterization,the research superimposes the process of regional geographic evolution as one of the criteria f
