黑龙江是农业大省,森林的多种服务功能对主产区粮食生产具有重要意义。黑龙江省粮食主产区的森林生态系统服务功能主要包括气候调节、涵养水源、减少土壤肥力流失、净化环境、生物栖息地、有机物质生产等。客观衡量黑龙江省粮食主产区的森林生态系统的服务效能,对于粮食主产区森林资源保护、生态建设及其科学制定粮食生产和生态建设规划具有重要意义。针对黑龙江省粮食主产区森林的生态系统服务功能进行了分析和评价,并提出了合理的森林资源保护对策和建议。结果表明森林资源对黑龙江省粮食主产区生态环境改善和黑龙江省农业(农村)可持续发展具有重要的意义。
Heilongjiang is a big agricultural province. The various service functions of forests are of great significance to grain production in the main producing areas. The main functions of forest ecosystem services in major grain-producing areas in Heilongjiang Province include climate regulation, conservation of water sources, reduction of loss of soil fertility, purification of the environment, habitat for biological resources and production of organic materials. Objectively measuring the service efficiency of forest ecosystems in major grain-producing areas in Heilongjiang Province is of great significance to the protection of forest resources, ecological construction and the scientific planning of grain production and ecological construction in major grain-producing areas. This paper analyzes and evaluates the ecosystem services of the main grain-producing areas in Heilongjiang Province and puts forward some reasonable countermeasures and proposals for the protection of forest resources. The results show that forest resources are of great significance to the improvement of ecological environment in main grain-producing areas of Heilongjiang Province and the sustainable development of agriculture (rural areas) in Heilongjiang Province.
