A Study On Land Reasonable Use Problems In The Daqing Oil Field Composite Region

There are more than one hundred and ninety resource cities in our country, the Daqing city is one of the typical oil field cities in most resource cities. Its oil field land quantity is big and oil field exploitation also makes an external effect to all other land use. The paper is established in the actual circs of the Daqing oil field land use and through on-the-spot investigation, has obtained the Daqing oil field land property right, land management, land utilization present situation and so on foundational data. According to the system analysis and the contrastive analysis, the quantitative analysis method of the information entropy, the land utilization integrated degree index to analyzing and researching land utilization ordered nature, the land utilization dominance and the land utilization integrated degree index in the Lasaxing oil field in the Daqing main production region, and discoveres that the land use's ordered nature and the land utilization integrated degree index has experienced the process which increases first reduces again in the Lasaxing oil field, explained that because of the rolling development of oil field causes the partial lands temporary desolation,moreover the lawn degradation, sand character, salt and alkali character are serious and the weed area increases. To further inspect oil field exploitation to the land ecosystem influence, through to reckoning the ecosystem service value in the Lasaxing oil field in1990-2004 year, discoveres during 14 years the ecosystem service value reduces nearly 45% in the Lasaxing oil field region, there are tow primary causes which brings to this result that one is oil field exploitation has taken the massive agricultural production and the ecology land, and on the other hand is the land vegetation coverage degree reduces, accordingly the ecosystem service value reduces. Uses the entropy scaling coefficient method to evaluating land ecological security situation in the Lasaxing oil field region in 2004 and the evaluating result had indicated that land ecological security level is lower and in the risk level in the Lasaxing oil field region in 2004 the land reclamation improvement situation is stern.On the base of recognizing clearly the problems of the Daqing oil field land use, considering the diplex demands of oil exploitation and land reasonable use and protection. Firstly beginning to studying on the principle and character of the land composite use, and then based on them, the paper exploringly compartmentalizes land composite region and analyses land composite circumstances of the various composite regions, and then considering the different traits of various composite regions, brings forward pertinence countermeasures and suggestions of land composite use in the different composite regions. On the base of the oil field land composite use, the paper puts forward the idea of the Daqing oil field land anew use and exploringly establishes the mechanism system of the oil field land anew use. Considering the precondition of the Daqing oil field land anew use, the paper studies the directions, approaches and guarantee measures of the Daqing oil field land anew use. At the same time, the paper also studies the property right of oil field land and the allocation of increment income when the Daqing oil field land turns into the city construction land. At last, by TOWS analytic method, the paper discusses the countermeasures of the Daqing oil field land use and brings forward a series of countermeasures and suggestions of land reasonable use.On the base of the problems of oil field land use and the demand of the land resource continuable use, on the one hand the paper analyzes and discusses the problems of oil field land composite use ,on the another hand the paper analyzes and discusses the problems of oil field land anew use in the recessionary period of Daqing oil field exploitation, but in virtue of shortage of the arts and crafts and technique of the ground project establishment of the oil field, the study of the composite use and anew use of the oil field land does not go deep into and it also needs to much more develop and improve in the future, makes it form a suit of reasonable, order and exercisable mechanism system of the oil field land anew use to have direction reasonable and continuable use of the oil field land.
