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.
