AB  - This dataset contains data on the spatial allocation of plants, weed invasion responses and soil ecological processes in artificial grassland ecosystems. The study explored the regulatory effect of plant spatial structure on weed invasion resistance by constructing different local plant patch size gradients (mixed sowing, 0.0625 m², 0.25 m² and 1 m² patches) and simulating different spatial heterogeneity conditions. The experiment monitored the aboveground biomass of local plants and invasive plants for two consecutive years, and simultaneously measured soil physical and chemical properties, including soil organic carbon (SOC), ammonium nitrogen (NH-N), nitrate nitrogen (NO-N), available phosphorus (AP), pH and soil phosphorus composition and other indicators.This dataset contains plant community and soil physical and chemical properties data obtained from the spatial allocation of artificial grassland species and weed invasion control experiments from 2024 to 2025. The main observation indicators include aboveground biomass of local plants, aboveground biomass of invasive plants, total aboveground biomass of communities, as well as soil organic carbon (SOC), nitrate nitrogen (NO-N), ammonium nitrogen (NH-N) and available phosphorus (AP), etc. The data covers the spatial configuration of 4 local plants and the treatment of 3 weed invasion, which can be used to analyze the impact of plant spatial configuration and weed invasion on artificial grassland productivity, invasion resistance and soil nutrient characteristics.
