What Is Intensive Distribution?

The concept of intensive land use originated from the study of agricultural use, and was first proposed in the land rent theory by classical political economists such as David Ricardo (1772-1823). The so-called intensive use of agricultural land refers to the concentrated input of more means of production and living labor on a certain area of land, and the use of advanced technology and management methods in order to obtain high yields and income on a smaller area A form of agricultural management. According to the composition of input of production factors, intensive use of agricultural land is divided into capital-intensive, labor-intensive and technology-intensive. Adding labor and capital to the currently used land is called intensive land use.

Land intensive use

The concept of intensive land use originated from the study of agricultural use, and was developed by David Ricardo (1772-1823) and others.

Land intensive use is essentially the relationship between land input and output, that is, the highest output is obtained with the least input on the land. The connotation expansion includes the following three levels of meaning:

1. Intensive use of land plots, which refers to a certain area

Comprehensive Evaluation of Urban Land Intensive Use

Land is the basis of urban social and economic development, and the effective supply of urban land is an important guarantee for urban economic development. In recent years, with the rapid development of economy and society, the continuous progress of urbanization and industrialization, a large amount of cultivated land has been occupied, and the contradiction between land supply and demand has become increasingly acute. At the same time, many cities are expanding in a "big cake" style, and urban land idleness and inefficient use are common. The fundamental way to resolve this contradiction is to tap internal potential. Therefore, it is particularly necessary and urgent to carry out research on intensive use of urban land.

Based on the theories and research methods at home and abroad, based on the intensive use of urban land and the status and characteristics of urban land use in Sichuan Province, this paper focuses on four aspects: land input level, land use degree, land use efficiency, and land use eco-environment quality. On the aspect, an evaluation index system for the intensive use of urban land was established. The overall level of intensive use of urban land in Sichuan Province from 1999 to 2004 was evaluated using the entropy method. The urban land was analyzed using the Spearman rank correlation coefficient method and SPSS cluster analysis Spatiotemporal characteristics of intensive use, and analysis of the influencing factors of intensive land use and the development trend of urban land use in Sichuan Province. The conclusions of the study are as follows:

(1) From 1999 to 2004, the score of intensive use of urban land in Sichuan Province increased year by year, and the level of intensive urban land continued to increase. The level of urban land investment in Sichuan Province showed a downward trend before 2002, and began to rise slowly after 2003. Prior to 2003, the degree of land use in Sichuan Province declined year by year, and only slowly began to increase in 2004. During the study period, the urban land use efficiency and the quality of the land use eco-environment in Sichuan Province increased year by year.

(2) Based on the results of hierarchical cluster analysis, the level of intensive use of urban land in prefecture-level cities in Sichuan Province is divided into four categories. Generally speaking, most cities with high levels of urban land intensive use are located in areas where the secondary and tertiary industries of the Sichuan Basin are relatively developed and the urban infrastructure is complete, while some old cities with traditional agriculture as their pillar industries score relatively low. . The level of intensive use of urban land is basically consistent with the comprehensive strength of cities across the province, and is roughly positively related to the level of economic development. From 1999 to 2004, there were significant differences in the level of land intensive use in the cities of Sichuan Province, but this gap gradually decreased during the study period.

(3) From 1999 to 2004, the level of intensive land use in urban areas of Neijiang City and Guang'an City increased significantly; the level of intensive land use in Guangyuan City, Suining City, Meishan City, Bazhong City, and Ya'an City did not increase significantly; and Chengdu City, Panzhihua City, Mianyang City, Leshan City, Nanchong City, and Dazhou City have seen a certain decline in the level of intensive land use, but the decline is not significant; the urban land intensification in Zigong, Chenzhou, Deyang, Yibin, and Ziyang Utilization levels are significantly reduced.

(4) The results of the research on the factors affecting land intensive use show that the level of land input has the greatest impact on the level of urban land intensive use in Sichuan, and the land use ecological environment quality has the smallest impact. It shows that the intensive use of land in prefecture-level cities in Sichuan province is mainly realized through the investment in land, and economic factors are the main factors affecting the intensive use of urban land. ^[1]

Promote intensive and economical use of land from six aspects. I. Studying the evaluation mechanism and system of intensive land use evaluation, insisting on strict land use standards to standardize intensive land use, normalize the evaluation of land intensive use, implement the evaluation and assessment of the entire process of land use, and improve the decision-making phase of project introduction Site evaluation. 2. Establish standardized factory buildings and actively guide industrial projects to be concentrated in the park; adopt reasonable land use costs to promote intensive land conservation; actively guide farmers to concentrate on new communities, organize the original construction land of rural residents, promote industrial structure adjustment and upgrade, and improve land use effectiveness. 3. Intensify the disposal of idle land, increase the supervision of post-approval land use, and promote the effective use of land; increase the investigation and punishment of illegal and illegal land use, and seriously investigate and deal with land violations. 4. Comprehensively sort out the existing land resources, tap the potential of connotative development, and further encourage construction projects to expand above-ground and underground space. There will be room for further improvement in the comprehensive utilization rate and building density of the park. V. Regulate the use of land for industrial projects outside the park, and support the use of land for important industrial projects identified by the departments of development, reform, industry, planning, and environmental protection of the real estate on the premise of conforming to the overall land use planning, urban planning, and industrial planning. 6. Under the control of the supply of new construction land, increase the vitality of the existing land stock, further link the new construction land indicators with the digested stock of live stock land, and promote the adjustment of the industrial structure. ^[2]
