摘　　要：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。Qinzhou City was 10 603 km^2 in total territory. Analysis and evaluation of eeo-sensitivity of Qinzhou City based on regional development revealed that areas moderate and low in eeo-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 eeo-sensitivity and development/construction, the city was divided into three types of regions, that is, highly ecorestrictive region, moderately eco-restrietive region and non-eco-restrietive 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.
