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.
