Study On Evaluation And Configurable Patterns Of Intensive Utilization Of Arable Land In Harerbin

As the essential material foundation of human' existence and development, cultivated land is the irreplaceable means of production in food and other agricultural products getting. It depends directly and indirectly on the cultivated land quantity and quality to develop agriculture, to improve people's life level and to develop the national economy. In order to ensure food security in China's and remain farmland unchanged or increased hard, the realization of the intensive use of arable land will have special significance. Therefore, the use of arable land intensive research will be imperative.Intensive land use is one of the core issues of arable land. How to establish a scientific assessment system, a reasonable evaluation method and an effective allocation pattern, is currently a hot issue in land scientific research.The paper was researched focus on envaluation of cultivated land intensive use and its allocation pattern from theory, method to instance aspects. First, explicit the content of cultivated land use. Cultivated land intensive use is a dynamic content and its standard is changing as the society and science developing. Second, the paper introduced some relative theories on cultivated land intensive use.Third, the paper introduced appraisal model of cultivated land intensive use based on PSR . The last, it discussed allocation pattern and relative measures of Harbin cultivated land intensive use.This paper explained cultivated land intensive use conception based on PSR starting with the man-land relationship, and esteblished the index system based on PSR model.Then the method of principle component analysis was adopted to calculate the cultivated land intensive use of 11 regions in Harbin with the formation of the index system and the result was graded. At last, it put forward the intensive use pattern for Harbin cultivated land based on appraisal result. Some of the main achievements of the paper could be summarized as follows: The first, from 2001 to 2005, all regions in Harbin had no significant change in cultivated land intensive use. According to the character of intensive use, all the regions could be divided into three parts: the first part included downtown, Acheng, Shangzhi, Bayan, Fangzheng. These regions had a increase in intensive use year by year . The second part included Shuangcheng , Binxian, Yanshou, Mulan and Tonghe.These regions had rise and fall in intensive use among these years, but had a increase on the total. The third part included Wuchang and Yilan; these two regions both had a decrease.The second, cultivated land intensive use in the western of Harbin was the most intensive, the southeastern was the second, the northern was the least, it was because of the different location and industrial structure of these areas. And the author used ARCGIS technology and renderd the intensive use of land distribution grading plans. The third, by analysis found that the intensive use of land in Harbin PSR system and the level of coordination was positive correlation. This showed that the PSR subsystems and internal coordination between the various factors of farmland to a large extent reflected the intensive use of a balanced, relatively high reliability model for information from the parties concerned. The fourth, the conventional model of sustainable high yield and high efficiency-saving model, stereo-Multi-level cycle model are the optimal models of cultivated land intensive use in future in Harbin. Finally, the writer researched intensive cultivated land allocation measures of Harbin: firstly, imply farmland restructuring to promote intensive use, secondly, strengthen construction of eco-agriculture base and optimize distribution of products, thirdly ,rely on the scientific progress to improve integrated benefit of arable land resources, forthly establish a information and monitoring system to ensure farmland quality and quantity, fively promote water-saving irrigation technologies and break a new road fitted for region, sixly strengthen land Consolidation to achieve scale and intensive operation.
