Abstract
|
The large population and the relatively insufficient cultivated land resource are our country’s fundamental reality, and they are also the important restricted factors that limit our country’s society and economy sustainable development. In order to alleviate this contradiction between people and land, the country implemented cultivated land requisition—compensation balance system. The purpose is to control occupation and protect farming land. The essence is to guarantee the national food security. At the same time, in order to avoid appearing the phenomenon of occupying superior cultivated and compensating inferior or quantity instead of quality, the supplementary farming land’s quantity and quality should all achieve a certain standard.This article is precisely under this big background, and takes "Study on the Construction of Project Quality Criteria of Supplementary Cultivated land" as the topic, analyses the existing problems of land consolidation, applies agricultural gradation achievement, puts forward the supplementary farming land not only to reach a higher request in natural quality, but also to achieve a certain standard in the project quality. The purpose is to make the reducing arable land owing to building and the supplementary cultivated land by land exploitation and consolidation almost equivalent. The research method combined theory with practice analysis and qualitative with quantitative, objectively ascertained the weight of supplementary cultivated land project quality factors in AHP method, uses integrative exponent method to confirm every project criteria’s cent and finally determine the project quality criteria of supplementary cultivated land.The article explicitly proposes that construction of the project quality criteria of supplementary cultivated land must embark actually from the land exploitation and consolidation project, guarantees the supplemented farming land general productivity, according to circumstance allowable, the technology feasible as well as the economy is reasonable and so on the principles, takes the present land exploitation and consolidation correlative standards, the regulations and the technical standard as the basis, use the existing achievement of agricultural land gradation, propose the engineering quality criteria that both manifests the regional characteristics and conforms to the inherent laws of land exploitation and consolidation .This article took TaiHangshan mountainous region in Hebei province as an example, launched the research of factors and weight of construction of engineering quality criteria of supplementary cultivated land. Firstly analyze the cultivated land reserve resources type and quantity of this area, then divide the cultivated reserve resources exploitation district, and choose the dominant and steady factors mainlyfrom the farmland flatting project quality criteria, farmland irrigation project quality criteria, the road project quality criteria and the zoology and environment project quality criteria, and objectively ascertained the weight of supplementary cultivated land project quality factors in AHP, used integrative exponent method to confirm every project criteria cent and finally determine the project quality criteria of supplementary cultivated land.;select the leading role factors that are important to soil natural quality of agricultural land gradation, such as the surface soil texture, the soil effective layer depth, the soil body configuration and the soil organic matter, take these as the factors of supplementary farming land soil natural quality criteria, and make the cultivated land project quality criteria even more rounded and perfect;at the same time using the agricultural land utilization grade achievement of this type area, enact the concrete productivity by using the standard grain and utilization grade index
