Soil Indicators

n this study, we hypothesized that the conversion of paddy fields to dry lands and forest lands would lead to a decline in soil quality. To test this hypothesis, we systematically collected soil samples under different land use types and analyzed their physical, chemical, and biological properties in the laboratory. Specifically, we selected representative samples from paddy fields, dry lands, and forest lands to ensure the data’s representativeness and reliability. For each land use type, we collected 90 soil samples and measured physical properties, such as soil texture; chemical properties, including pH, nutrient contents (e.g., nitrogen, phosphorus, potassium), and organic matter content; as well as biological properties, such as microbial diversity indices. By comparing the soil properties across different land use types, we aimed to investigate the impact of land use changes on soil quality and to provide a scientific basis for future land management and ecological restoration efforts. The data analysis will reveal the extent of soil degradation caused by the conversion of paddy fields to dry lands and forest lands, thereby supporting the development of effective land use policies.本研究假设，将水田转化为旱地与林地的土地利用变化，会导致土壤质量下降。为验证该假设，本研究系统采集了不同土地利用类型下的土壤样品，并在实验室中对其物理、化学与生物学特性开展分析。 具体而言，为保障数据的代表性与可靠性，研究团队从水田、旱地与林地中选取了具有代表性的样品。针对每一类土地利用类型，均采集了90份土壤样品，并测定了相关指标：包括土壤质地等物理特性，pH值、氮磷钾等养分含量与有机质含量等化学特性，以及微生物多样性指数等生物学特性。 本研究通过对比不同土地利用类型下的土壤特性，旨在探究土地利用变化对土壤质量的影响，为后续土地管理与生态修复工作提供科学依据。数据分析可明确水田转化为旱地与林地过程中引发的土壤退化程度，进而为制定合理有效的土地利用政策提供支撑。
