Abstract:

The low-carbon utilization of cultivated land has been a critical path to promote the sustainable development of agriculture. Heilongjiang Province, as an important grain-producing area in China, its low-carbon development of cultivated land is of demonstration significance for the national green economic transformation. Firstly, the paper defined the relevant concepts of low-carbon utilization of cultivated land, and analyzed the current situation of cultivated land utilization in Heilongjiang Province quantitatively from three dimensions of economic basis, planting structure and crop yield, and evaluated the performance of low-carbon utilization of cultivated land based on the principal component analysis method from 2008 to 2023. The results showed that the comprehensive performance demonstrated a fluctuating upward trend during the 16 years, with the highest score in 2017 (0.88 points) and the lowest score in 2008 (-1.65 points). The process of performance evolution could be divided into three period, rapid development period (2008 to 2015), declining period (2016 to 2021) and recovery period (2022 to 2023). The study identified problems further such as insufficient economic support, technological lag and weak low-carbon awareness of farmers, and proposes targeted policy recommendations. Aiming to the problems, the paper provided the targeted countermeasures and suggestions in order to provide a reference for low-carbon development of cultivated land in Heilongjiang Province.
