Distribution Characteristics of Biomass Resources in Gansu Province

Year: 2026

Type: article

Abstract: Gansu Province has abundant agricultural biomass resources, but the gap between the biological yield of biomass and available quantities, along with strong spatial heterogeneity, restricts efficient bioenergy utilization. This study quantifies four categories of agricultural biomass across 85 county-level units in Gansu, evaluates relative enrichment density via the Biomass Resource Location Quotient (BRLQ), and identifies spatial agglomeration patterns using global and local spatial autocorrelation. The results show a significant structural mismatch: total biological yield of biomass reaches 46.41 million tons, while available resources are only 12.13 million tons, with crop straw as the dominant available feedstock. The Longdong Loess Plateau has the highest enrichment density (BRLQ = 1.588). No significant global spatial agglomeration is observed, and significant clusters are confined to local small areas. This study provides quantitative support for zonal bioenergy planning in Gansu.
