基于区域开发的钦州市生态敏感性分析及防控对策

对基于区域开发的钦州市生态敏感性评价结果表明:中、低敏感区占全市土地总面积64.49%,高敏感区和非敏感区分别占19.22%和16.29%.通过对生态敏感与开发建设关系的分析,划分出生态高约束、生态适度约束及生态非约束3类区域,为全市工业化、城市化空间发展提供参考.从自然生态保护、水源涵养与供给、自然灾害影响及建设用地拓展4个方面提出维护区域生态安全、预防和控制生态敏感危害的对策.

Eco-Sensitivity and Countermeasures Based on Regional Development-A Case Study of Qinzhou City

Qinzhou City was 10 603 km2 in total territory.Analysis and evaluation of eco-sensitivity of Qinzhou City based on regional development revealed that areas moderate and low in eco-sensitivity accounted for 64.49% of the total land area,and areas high and non in eco-sensitivity for 19.22% and 16.29%,respectively.Based on analysis of the relationship between eco-sensitivity and development/construction,the city was divided into three types of regions,that is,highly eco-restrictive region,moderately eco-restrictive region and non-eco-restrictive region,which may serve as reference for development of the industrialization and urbanization of the city.Meanwhile,countermeasures are presented for maintenance of regional eco-safety and prevention and control of eco-sensitive hazard from the aspects of natural ecology preservation,conservation of water resources and water supply,impact of natural calamities,and expanding of construction land.
