[Objective] Based on the original regionalization of Hanzhong City

Shaanxi Province in 1986

to complete the link between provincial and municipal divisions

and further integrate the characteristics of soil erosion in Hanzhong City in order to provide supports for the soil and water conservation work in this area.[Methods] By overlapping map analysis

and combined with the natural conditions and the development trend of soil and water loss

soil and water conservation zone in Hanzhong City was re-divided.[Results] The city was divided into four areas including the northern water source conservation ecological maintenance area

the central human settlement environmental water quality maintenance area

the western water source conservation water quality maintenance area

and the southern soil conservation ecological maintenance area.[Conclusion] The northern water source conservation ecological maintenance area should be paid attention to the protection and rational development of natural forest and grass resources. Deforestation should be strictly prohibited

and the shifting cultivation in steep slopes rim should be changed into strip intercropping. The central human settlements water quality maintenance area should be paid attention to revetment of beaches

rectify rivers

continue to do a good job in urban greening

build high-standard basic farmland

optimize the ecological agriculture environment

and improve the living environment. The western water source conservation water quality maintenance area should improve the ability to control surface source pollution. For the types of land used for sloping farmland

excavation exposed surface and grassland

remediation and vegetation restoration should be carried out well to maintain the water quality of the water source area. In the southern soil conservation ecological maintenance area

it is necessary to carry out hill closure and afforestation in a certain area of sloping farmland and some gentle slopes above 25°

returning farmland to forests and grassland

so as to effectively protect forest grass and soil resources

at the same time

economic forest fruits with high economic benefits and remarkable ecological benefits should be promoted.
