On Conditions and Capacity of High Standard Basic Farmland Construction in Hilly Area---Taking Rongchang County of Chongqing as a Case
The construction of high standard basic farmland is not only an innovation of farmland-protection system under new situation,but also an essential way to transform the pattern of protecting farmland from assuring the quantity to assuring both the quantity and quality.In this paper the conditions of high stand-ard basic farmland construction in Rongchang county has been analyzed from the three index levels of culti-vated land slope,centralized contiguous degree and soil layer thickness,discussing construction condition of high standard basic farmland in hilly area of Chongqing,referring to the policy of “the construction cri-terion of high standard basic farmland (trial)”,basing on the investigations of areas which conditions meet the construction condition of high standard basic farmland,directing at the specificity of cultivated land in hilly area,and also combining to the 520 mu assignment of Chongqing.Results showed that the construc-tion of high standard basic farmland standards should be lower than the national construction standards un-der the cultivated land resource endowment of hilly region.Slope,effective soil layer thickness,concen-trated degree of cultivated land,probability of irrigation and the agricultural industry scale have been se-lected to conduct potential evaluation of the high standard basic farmland construction,combining with po-tential space layout,key demonstration zones of the high standard basic farmland construction are divided, and industrial cores are divided which are combined with characteristic industry,making the divided results more scientific and reasonable.
