Abstract


Land use is a dynamic concept. The land use structure refers to the proportion of the entire land area of ??all kinds of land. It reflects the various departments within a given area of ??land, and the proportion of undeveloped land use, expressed as a percentage of the total area of ??each land. The proportion of farmland, woodland and pasture, generally but also reflect the characteristics of the structure of agricultural production in a region. Compatible with the land natural form of land use structure is consistent with the structure of demand and use of existing structure, which discovered the problem to grasp the law. Moving average, weighted moving average and exponential smoothing values ??the three steady trend-forecasting methods, given the relative error of the three prediction methods, which can compare three methods of prediction accuracy. Applications Markov forecasting techniques to predict the City in 2006 and 2009 land use structure change, the analysis of the changes in the characteristics and laws of the land use structure change over time, in order to achieve the understanding of the agrarian structure of the region is the status quo in general grasp and future development trends. Number of Qiqihar urban areas from 1985 to 2002, 18 years to the structure of land use types and time varying characteristics and inter-district Administrative Region Basic spatial analysis unit, using the degree of land use change models as well as strength index analysis of land use changes Qiqihar City, the degree of land use in the past 18 years and its the differentiation characteristics change, differentiation characteristics of each type of land use change intensity. Through the dynamic changes of land use types in the research analysis, clear the problems and challenges faced by the Qiqihar urban land use structure; Qiqihar urban land development and utilization of the actual establishment of the structure of the rational use of the mode, and rational land use measures and means are also discussed. As the speed and scale of construction land and transportation land continues to accelerate and intensify a significant change has occurred, so that the land use structure, therefore, the accuracy of the science to understand and grasp the trend of arable land and land-use changes in the structure of the region, for the rational distribution and optimize the structure of agriculture has important theoretical and practical significance, as well as for the prevention of further land degradation and improve land productivity and economic efficiency, improve the ecological environment and promoting the sustainable development of the agricultural economy.
