Mainland China is covered by a 50-km equal-area grid containing 367,017 occurrence records for 884 alien plant species across 4,129 grid cells. The dataset, created by Lin Chen, integrates GBIF records with Chinese digitized local records and includes derived grid-level richness and hotspot indicators. It was last updated on April 12, 2026, and supports modelling with climate, topographic, vegetation, soil, and anthropogenic predictors.
Use Cases
- Modeling alien-plant invasion hotspots based on integrated richness indicators like hotspot_q90 and hotspot_q80.
- Analyzing the relative contribution of GBIF versus local data sources to species richness using the data-source status field.
- Training machine learning models (e.g., XGBoost) for spatial prediction using climate, topographic, and anthropogenic predictors.
- Interpreting ecological drivers of invasion using SHAP, GAM-smoothed SHAP response curves, and GeoShapley methods.
Strengths
- Contains 367,017 harmonized occurrence records for 884 alien plant species.
- Data is integrated from two sources (GBIF and Chinese local records) and standardized to a 50-km grid covering 4,129 cells.
- Includes derived analytical products like integrated richness, GBIF richness, local richness, richness gain, and hotspot indicators.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- The description does not specify the temporal range of the occurrence records.
- Data may reflect geographic or source bias inherent to the combined GBIF and local records.
Provenance
- Source
- Lin Chen via figshare.
- Collection Method
- Records were harmonized from an integrated naturalized-plant database combining GBIF records with Chinese digitized local records.
