| One of the important elements that affect the world environmentalchange is the change of land use, land use change is the most obvious area islocated in farming-pastoral zone of northern China in the northeast of thefarming-pastoral zone in Inner Mongolia. But compared with the westerndesert or sand areas in China, the precipitation, low temperaturecharacteristics. Due to human activity is the overuse and incorrect policyleads to the area of cultivated land area of growth, environmental degradationand ecological imbalance. Some related research results show that thebackground is not natural for the increased amount of arable land, while theanthropogenic interference is increasing, the most obvious since the foundingof the practice of land policy, so this paper following the conclusion of theformer research, it is necessary for arable land to increase the cultural factorsis studied, at the same time for cultivated land protection and provides thebasis for ecosystem recovery.This paper selected the typical farming-pastoral zone in Inner Mongoliaarea is one of--ALuKeErQinQi, for example, using in the study area in1986,1996and1986, LANDSAT5LANDSAT TM images and2013-8OLI remotesensing image and statistical data from1946to2013and policy documents asthe main data source, application of remote sensing, geographic informationsystem, statistical analysis and the method of qualitative description, analysisand research area of nearly60years policy evolution and cultivated landchange, and the relationship between the policy and the anastomosis of thecultivated land obtained results as follows:1.Since its establishment, the ancient of Inner Mongolia autonomousregion ALuKeErQinQi land policy is basically consistent with the national policy, historic changes have taken place in nearly60years of land policy.Before reform and opening up land reform to establish people’s communesstage is the reform of land ownership and land use rights. From the earlystages of reform and opening up to the21st century is the main system ofhousehold contract responsibility system as the reform of land use in thecenter of the method. In the21st century, all kinds of policy is more tend toecological construction, cultivated land protecting environment recovery.2.The aru khorchin nearly60years flag has experienced the increase ordecrease the volatility process of cultivated land area. From1946to2013, thearable land on the rise, increased932.42km2, the proportion of the total landarea increased by9.3%. QuanQi land before sliding flat characteristics offluctuations in the90s, has obvious periodic changes in the90s.Farming line extension area mainly concentrated in the flag of the woodriver, and horsepower JiMu fall river and Silas wood river on both sides of therelatively low altitudes, north mountain and low mountain area of cultivatedland is very scattered distribution. On the whole this flag agricultural frontiergradually moving north.3.There are many factors that can influence of arable land, but the effectis more prominent is the national macro policy. The analysis results show thatthe nearly60years the flag of cultivated land change and the policy ofgovernment, there is a close relationship. National or local policies directlyaffect the cultivated land change, inappropriate policy directly produce blindexpansion of the cultivated land; And reasonable policies and methods toprotect arable land, protect the environment.After the trend of land policy must be combined with local actual andecological environment protection. Returning farmland to forest to link withagricultural guarantee, will not appear after the farmers meet disaster yearChiLiang unwarranted condition; The use of advanced technology to improveagriculture production, intensive management, the development ofcompetitive industries, thus protecting farms, protect pasture. Required putforward a series of practical and effective policy, formulate relevant laws and regulations, the reasonable policy of institutionalization and legalization. |
