Abstract: In order to understand the current situation of heavy metal pollution in greenbelt soil of Huaihua City, this research studied the quantitative characteristics of heavy metal pollution in different regions and different types of greenbelt soil of Huaihua City, by using INNOV-X soil heavy metal measurement instrument and the method of single factor pollution index and the synthesis pollution index. Results showed that: both the individual pollution indexes of Cr and As element in the three regional greenbelt where located in city center, Yingfeng area, Tuoyuan area were greater than 1, manifesting as light pollution. The synthesis pollution index of three regional greenbelts was greater than 1, also manifesting as light pollution. And the changes showed certain regularity, the pollution degree had the trend of increasing gradually from suburbs to city center. The individual pollution indexes of Cr, As and Cu element in the road greenbelt, the public greenbelt of Huaihua City were all greater than 1, manifesting as light pollution or moderate pollution. Except for the productive greenbelt, the synthesis pollution indexes of other greenbelt types were greater than 1, manifesting as light pollution. Different greenbelt types showed different levels of pollution, road greenbelt > public greenbelt > accessory greenbelt > productive greenbelt. In view of the above situation, adopting preventive and control measures to control the heavy metal pollution in greenbelt soil of Huaihua City is very important to the construction of ecological livable city.
