| Cultivated land is the essence of land, which is a very scarce and irreplaceable natural resource and the agricultural production factor. Several issues are being faced by He Nan province nowadays, such as populations, resources, environmental protection and food, which are related with the earth. On the one hand, the cultivated land quantity per person had in Henan Province is few, the overall quality level is low, the developed degree is high, the not using land is mostly distributed in the mountainous area and the hills, the farming resources reserved are insufficient, thus we must excavate cultivated land using potential fully; On the other hand, with the increase of population and the quicken of industrialization and urbanized, construction land quantity increases unceasingly, the contradiction of land's supply and demand incisive day by day. Therefore, as a province located in the Central Plains, with the population of 98 million, to improve the provincial land-use efficiency and promote land-intensive conservation for Henan Province, is directly attached to the realization of food security, sustainable agricultural development, national economic development and social stability.First, This paper analysis 2002-2007 planted crops the resources quantity change, the fluctuation to Henan Province to flow to, to plant crops the region dynamic change and the farming changes the reason to carry on the analysis, discovered that in the last few years the Henan Province farming total quantity maintained the dynamical equilibrium, the average per person farming reduced continually year by year, the land development was increases the farming the fundamental mode, the construction land takes the farming the proportion to be getting bigger and bigger; Then in 2007 plants crops the use correlation data material take the Henan Province 18 prefectures as the foundation, selected the investment intensity, the degree of utilization, to deliver the effect three criterion level target, 11 target level target, used the analytic hierarchy process to carry on the appraisal intensive to the Henan Province various prefectures cultivated land using the level, in the whole looked, north Henan Province and south the intensive degree of utilization was high, middle was next, the west was low; Is following closely in the analytic hierarchy obtained data foundation, uses the criterion level data, the use cluster analytic method, the Henan Province 18 prefectures will converge 5 kinds, between the analysis contrast similar region cultivated land intensive use common ground and the different kind of region difference and the characteristic, from the environment, the economic development level, the area development strategy, the industrial structure and the population five aspects analyzed thoroughly has created the difference the reason; Finally analyzes in above in the foundation, proposed target-oriented enhances Henan Province to plant crops saves the intensive use level countermeasure suggestion. |
