Abstract: |
How to scientifically and orderly carry on high-standard prime farmland construction and analyze the main obstacles was the key for its construction. Based on multi-source data of the production of high and stable yield, considering the local conditions for the growth of crops and farmland construction, this paper used the technique for order preference by similarity to an idea solution(TOPSIS) and the obstacle degree model to analyze the time sequence and obstacles diagnosis of high-standard prime farmland construction in Loubei. The results showed that (Ⅰ)high-standard prime farmland construction was mainly divided into three periods, the immediate construction areas mainly distributed in the southeastern of Tuanjie town, east of the Korean township, Fengxiang town in northwestern south and Zhaoxing town in the western region. The mid-construction area accounted for 55.18 percent of the total arable land. The long-term construction area mainly distributed in Mingshan town and the northern of Hebei town.(Ⅱ) The obstacle factors mainly concentrated in the infrastructure construction and location using condition two aspects, of which ditch density contribution rate was higher in different construction period.(Ⅲ) the influence degree of the obstacle factors in different construction periods was different. The construction time sequence and obstacles diagnosis can provide theoretical basis and feasible reference for the construction of area′s high-standard prime farmland. |
