摘要
上海市已经陆续开展五批次市级土地整治项目,土地整治流程与技术业已成熟。但目前对于土地整治规划主要基于新增耕地数量与基础设施建设等,而较少考虑生态因素。本文以植物、土壤动物、鸟类、两栖类、昆虫、浮游生物为调查对象,对上海市金山区土地整治项目区进行生态调查。调查结果发现,该区域鸟类、蛙类、昆虫物种多样性较高,乡土植物应用比例低,入侵植物分布范围广泛,土壤动物在灌溉水田以及荒地密度较低,河道中浮游生物密度较高。由此建议:加强乡土树种的利用构建多层次、多种类的植物群落;合理规划灌溉水田用地面积及耕作条件,利用好荒地和未利用地;种植多种水生植物,增强水生态系统稳定性。
Shanghai successively carried out five batches of city-level land consolidation projects.Land consolidation processes and technologies have evolved.However,presently,the land consolidation plan is based on the amount of newly added cultivated land,infrastructure construction,among others out of ecology.Taking plants,soil animals,birds,amphibians,insects,and plankton as survey objects,this study conducted an ecological survey on a land improvement project area in Shanghai.According to the survey results,the species diversity of birds,frogs,and insects in this area was relatively high,the proportion of native plants used was low,the distribution of invasive plants was wide,the density of soil animals in irrigated paddy fields and wastelands was low,and the density of plankton in the river was relatively high.There are suggestions to improve the land consolidation plan,such as strengthening the use of native tree species to build a multilevel and multi-type plant community,rationally planning the area of irrigated paddy fields and farming conditions,making good use of wasteland and unused land,and planting a variety of aquatic plants to enhance the stability of the aquatic ecosystem.
