A dataset of dry and wet deposition of nitrogen and phosphorus at Dali, Yunnan, Agro-Ecosystem, National Observation and Research Station (2021 -2023)ure and animal husbandry areas of low latitude plateau areas from 2020 to 2022

Dry and wet deposition of nitrogen and phosphorus refers to the process in which nitrogen and phosphorus in the atmosphere reach the ground through deposition, entering the material cycle of terrestrial ecosystems. Dry and wet deposition plays a significant role in the input of nitrogen and phosphorus pollution in the environment. As a country with a large agriculture and animal husbandry, it is of great significance for China to understand the nitrogen and phosphorus dry and wet deposition load originating from farming and livestock activities. This understanding can help evaluate the ecological effects of nitrogen and phosphorus deposition, guide environmental pollution control, and promote sustainable development in the farming and livestock industry. This dataset provides nitrogen and phosphorus dry and wet deposition data from 2021 to 2023 at observation points at the Dali, Yunnan, Agro-Ecosystem, National Observation and Research Station in Xizhou Town, Dali City, Yunnan Province. This area is a typical farming and animal husbandry region within the watershed, with a livestock population of 60 heads and a total area of 200 mu for farmland. The main cropping systems include rice-oil rotation and rice-bean rotation representing a typical regional planting method.The dataset provides information on total nitrogen, total phosphorus, nitrate nitrogen, ammonium nitrogen dry deposition, and wet deposition flux at both the farmland and livestock environment observation points. The aim of this dataset is to study the impact of farming and livestock activities on environmental nitrogen and phosphorus dry and wet deposition and to provide data for calculating the nitrogen and phosphorus deposition load in the farming and livestock industry. Additionally, this dataset can provide data support for lake pollution control in the low-latitude highland areas.

氮磷干湿沉降是指大气中的氮、磷物质通过沉降作用抵达地表，并进入陆地生态系统物质循环的过程。干湿沉降是环境中氮磷污染输入的重要途径。作为农牧业大国，明晰农牧业活动产生的氮磷干湿沉降负荷，对我国而言具有重要意义。该认知可用于评估氮磷沉降的生态效应、指导环境污染治理，并推动农牧业可持续发展。本数据集涵盖2021年至2023年，位于云南省大理市喜洲镇的云南大理农业生态系统国家野外科学观测研究站观测点的氮磷干湿沉降数据。该区域为流域内典型农牧业区，畜禽存栏量60头（只），农田总面积200亩。主要种植制度为稻油轮作与稻豆轮作，属于区域典型种植模式。本数据集包含农田与畜禽环境观测点的总氮、总磷、硝态氮、铵态氮干湿沉降通量数据。本数据集旨在探究农牧业活动对环境氮磷干湿沉降的影响，并为核算农牧业氮磷沉降负荷提供数据支撑。此外，本数据集可为低纬度高原地区的湖泊污染治理提供数据支持。
