Sustainable management of soil quality resources has become an important issue in international environmental management. Through long-term monitoring and investigation, we can grasp the temporal changes in soil properties, which is used by countries as a basis for planning policies on land resources development and use, agricultural development, environmental and ecological impact assessment, and even climate change mitigation and adaptation. This project reviewed the establishment of basic data related to soil resource survey in Taiwan, and conducted 12 representative soil profile surveys, completed 52 layered soil collection and soil property analysis, to build the necessary soil characteristic parameters for pollution transmission evaluation and risk assessments. Organic carbon storage of the rural soils has also been calculated. And propose a blueprint for the representative soil profile on slopes. Persistent organic pollutants (POPs) and emerging contaminants in soil are targets that concerned in this project, 224 POPs monitoring sites and 20 park soils are collected and analyzed respectively. Most of the samples contained less than 20 ng I-TEQ/kg of dioxin. The concentrations of other items are not abnormal or much lower than the administrative concentration values of each country compared with the overseas monitoring values, and the risk assessment results are within the acceptable range. The results of the soil investigation data have been established in the national soil properties database. After reviewing the overseas management trends and the results of the functional zoning of the Spatial Planning Act, we propose to adopt a graded zoning approach to guide the implementation of soil resource conservation and soil quality policies through the formulation of appropriate regulations and a proactive management structure. The project also assisted in the promotion of soil quality survey results, such as the World Soil Day, by producing graph cards, videos, posters, educational training, and expert consultation meetings.
