- 摘要:
- 黑龙江省是我国重要的商品粮基地，耕地总面积、人均占有耕地面积、粮食商品率均居全国首位，黑龙江省耕地资源安全与否直接影响国家耕地与粮食安全。以全国最大的商品粮基地——黑龙江省为研究区域，从耕地自身安全、经济安全、社会安全以及生态安全角度出发，结合黑龙江省耕地资源的实际，构建耕地资源安全评价指标体系，运用层次分析法，对黑龙江省1998-2007年间耕地资源安全状态进行定量分析与综合评价。结果表明：不同时期黑龙江省的耕地安全状态并不一致，1998-2001年耕地资源安全处于持续恶化阶段，2002-2007年耕地资源安全处于波动变化阶段，整体处于相对安全状态。全部评价值仅在2001年进入稍不安全行列，其余均处于相对安全值区间，耕地资源社会功能与生态功能评价结果基本与综合评价值整体态势相一致。
- Abstract:
- Heilongjiang province is an important base for marketable grain production in China, whose total area of cultivated land, per capita cultivated area, and output of foodstuffs are all in the first place. The state of cultivated land resources of Heilongjiang province influences the security of national cultivated land resources and food security directly. This paper took Heilongjiang, the biggest base for marketable grain production in our country, as research region, from the aspects of cultivated land own security, economic security, social security and ecological security and combined with practical situation of Heilongjiang cultivated land resources, to establish evaluation index system and use method of analytic and evaluation hierarchy process to analyze the operation status of the security of cultivated land resources in Heilongjiang from 1998-2007.The results showed that the security state of cultivated land in Heilongjiang was different from period to period, the stage of the continued to deteriorate from 1998 to 2001, the state of fluctuation changed from 2002 to 2007 and the overall state is at a relatively security situation. Only the evaluation value of 2001 entered into the ranks of insecurity and the rest are in a relatively safe range, the social function and ecological function of land resources are basically the same as the trend of comprehensive evaluation.
