Spatio-Temporal Patterns of Carbon Storage Derived Using the InVEST Model in Heilongjiang Province, Northeast China

Carbon storage is an important component of ecosystem services. Under climate warming and human activities, land use/land cover (LULC) have been undergoing tremendous change, leading to spatio-temporal variations in carbon storage. Based on seven series LULC data combined with module Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model, spatial-temporal changes types were analyzed estimated for Heilongjiang Province, Northeast China. Results show varied among different LULC. Forest cropland are the dominant China, accounting 46–49% (20.90 × 10 4 –22.12 km 2 ) 30–37% (13.56 –16.70 total area. Areal extents forest, grassland, unused declined from 1980 2015, by 1.22, 0.84, 1.11 , respectively; while those construction expanded, 3.14 0.08 respectively. From displayed consistent change trends types: decreased 236.22, 116.61 21.82 6 Mg C, increased 414.65 0.99 The study region was 6,863.06 –6,907.64 which cropland, grassland major contributor (6,778.75 –6,840.57 C). Due conversion large facilitated formation sinks thus enlarged 45.36 C 2015. Frequent forest fires, urban expansion, farmland reclamation, engineering factors LULC, accelerating permafrost degradation obvious Therefore, estimation can provide support implications evaluation services cycle.
