GIS-based ecological sensitivity analysis in Jiaozuo

Abstract：Based on current data of eco-environment and former research results, ecological sensitivity in Jiaozuo was given thoroughly analysis by selecting regionally representative factors and using the factor-overlap method of GIS.The model of eco-environmental sensitivity in Jiaozuo was established.Four classes of ecological sensitivity ranging from extreme to low were generated, which are extreme sensitivity region, junior sensitivity region, weaker sensitivity region and non-sensitivity region.Some advices and countermeasures for different regions were put forward to provide valuable references for the the regional spatial planning and regional eco-environment protection.The results show that about 30.7% of surveyed area belongs to upper moderately-sensitive ecological region, which means the sensitivity is moderate.
