Carbon Storage Dynamics in the Lower Yalong River Basin from 1986 to 2021

A geospatial dataset assesses carbon storage dynamics in the lower Yalong River Basin from 1986 to 2021. It was created by Borui Wang using Landsat imagery, random forest land-use classification, and the InVEST carbon storage model. The data shows a 7.07% decline in wet season carbon storage and a 6.44% decline in the dry season over the study period.

Use Cases

• Analyzing the relationship between hydropower construction phases and carbon storage changes based on the stage-based assessment approach.
• Identifying carbon-sensitive areas for ecosystem protection based on spatial patterns of change in the 5 km buffer zone and valleys.
• Modeling the impact of land-use transitions, such as forest reduction and construction-land expansion, on regional carbon budgets.
• Comparing carbon storage dynamics between wet and dry seasons over a multi-decadal period.

Strengths

• Covers a 35-year time series from 1986 to 2021, enabling long-term trend analysis.
• Uses a multi-method approach integrating Landsat imagery, random forest classification, and the InVEST model.
• Provides specific percentage changes in carbon storage for wet (7.07% decline) and dry (6.44% decline) seasons.
• Applies a stage-based assessment aligned with hydropower development periods (pre-construction, construction, joint operation).

Limitations

• The dataset is very small (27.4 KB), suggesting it may be a summary document rather than the underlying raw or processed geospatial data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative modeling.
