镇域土地生态安全综合评价研究——以重庆市丰都县十直镇为例
- Title:
- Comprehensive Evaluation of Land Ecological Security at Town Level—A Case of Shizhi Town in Fengdu County, Chongqing
- 分类号:
- X826
- 摘要:
- 以重庆市丰都县十直镇18个村（居委）为例，构建土地生态安全评价指标体系，以2011年数据为基础，运用综合分析法对其进行土地生态安全评价，以期判定影响其土地生态安全主要因素的重要性程度，并提供其土地生态安全未来的发展方向。结果表明：（1）总体上十直镇18个村（居委）的土地生态安全存在风险，但各村（居委）之间存在一定的差异，土地生态安全处于良好级的村1个，处于临界安全级的村（居委）13个，处于敏感级的村4个。（2）从空间分布来看，十直镇18个村（居委）的土地生态安全度从镇中部分别向西北方向和东南方向递减。（3）十直镇土地生态安全主要影响因素的重要性程度有差异，即地形条件 > 土地利用 > 土地质量安全 > 土地承载力安全，且各村（居委）之间有着明显的空间差异。（4）根据各个村（居委）的发展目标和实际情况，可把十直镇划分为城镇生态区、现代农果生态区、生态保护区和农业生态区共4个生态功能区。
- Abstract:
- This paper took eighteen villages, located in Shizhi town of Chongqing, as the examples and constructed an evaluation index system to assess land ecological security of the town by employing comprehensive analysis method based on the data of 2011, and explored the importance of its influencing factors of land ecological security, and then provided suggestions for future development of land ecological security in Shizhi town. The results showed that: (1) the land ecological security in Shizhi town was at a low level in general, but the diversity of land ecological security still existed among eighteen villages: one village was in a good state, thirteen villages were at a tipping state, while the other four villages were at a sensitive state; (2) the land ecological security viewed from spatial distribution was decreasing from middle to northwest and southeast; (3) the importance of influencing factors of land ecological security in Shizhi town had an obvious difference. Topographic condition was the most important, land use situation and land quality security were less important, while land carring capacity was the least important, and each village had obvious spatial difference of each influencing factor; (4) the whole town could be divided into four functional zones, which were urban ecological zone, modern fruit growing zone, ecological protection zone and agricultural ecological zone.
