- 摘要:
- 耕地利用安全是保护耕地和保障国家粮食安全的基础。以松嫩平原北部典型地区齐齐哈尔市为研究区，从耕地利用生态安全、耕地利用经济安全以及耕地利用社会安全三方面，构建了耕地利用安全评价指标体系，运用功效评分法，对齐齐哈尔市2002-2008年耕地利用安全状态进行了定量分析和综合评价。结果表明：2002-2008年，齐齐哈尔市耕地利用安全级别存在一定的差异，且总体呈现不稳定的波动状态。其中2002-2004年耕地利用安全处于临界状态；2005年耕地利用达到安全状态；2006-2007年耕地利用安全级别急剧下降；2006年为临界安全级别；2007年为不安全级别；2008年耕地利用安全状况有所好转，但仍处于临界安全状态。研究表明，耕地复种指数、耕地受灾面积等耕地利用经济指标与耕地利用社会指标是影响耕地利用安全的敏感因素。
- Abstract:
- Security of land use is the basis for the protection of cultivated land and the protection of national food security. This paper took the typical areas of Qiqihaer City in the northern region of Songnen Plain as the study area, and built security evaluation index system of land use with three issues, such as ecological security of land use, economic security of land use and social security of land use. The land use safety of Qiqihaer during 2002-2008 was quantitatively analyzed and comprehensively evaluated by using the method of efficiency scores. Evaluation results showed that 2002-2008, the security level of land use is different from each year and the present instability in overall volatility of the state. During 2002-2004, land use security level fluctuations were in the critical security status. In 2005, the land use security level got to a safe state. During 2006-2007 security situation of land use declined sharply and 2006 as the critical level of security while 2007 to unsafe level. Security of land use in 2008 significantly increased, but security is still in critical condition. Studies have shown that cultivated land use economic security and cultivated land utilization of social security indicators, such as the repeat of planting crop on cultivated land and the area of cultivated land disaster, are the important sensitive factors that impact the security of land use.
