摘要: 氮磷干湿沉降是指大气中氨磷通过沉降方式到达地面,进入陆地生态系统物质循环的过程,干湿沉降在环境氨磷污染输入中占据重要比例。我国是种养殖业大国,摸清源于种植业和养殖业的氮磷干湿沉降负荷,对评估氨磷干湿沉降生态效应、指导环境污染治理、促进种养殖业绿色发展具有重大意义。本数据集为云南大理农业生态系统国家野外科学观测研究站农田综合观测场观测点和养殖环境观测场观测点 2021-2023 年氨磷干湿沉降数据。观测点位于大理白族自治州喜洲镇,为流域内典型种养殖区域,养殖场常年养殖量为60头,农田面积为200亩,以稻-油,稻-豆轮作为主,是典型的区域种植方式。数据集数据项包含农田综合观测场观测点和养殖环境观测场观测点总氮、总磷、硝态氮、铵态氮干沉降及湿沉降通量等信息。数据集相关样品采集、检测、质量控制及数据审核过程均参照行业标准、规范,保证数据准确、可靠、有效。旨在研究种养殖业影响下环境氨磷干湿沉降,向种养殖业氨磷干湿沉降负荷核算提供数据基础,为低纬高原区湖泊污染治理提供数据依据。
