What are the benefits of intensive use of agricultural land? It is better to have specific data and examples, please ~

Intensive land use is essentially the relationship between land input and output, that is, the highest output is obtained with the least input on land, and its connotation expansion includes the following three meanings: 1, and intensive land use refers to the intensive land use of a certain land use type in the region. 2. Intensive land use refers to the intensive land use of the same land use type in the region. 3. Intensive use of regional land mainly refers to the optimal allocation of land resources according to the natural attributes (land economy, ecology and applicability) and social attributes (market supply and demand, urban development demand and social and economic development demand) of limited land resources. (1) 1999 ~ 2004, the score of urban land intensive use in Sichuan province increased year by year, and the level of urban land intensive use continued to improve. The level of urban land investment in Sichuan Province showed a downward trend before 2002, and began to rise slowly after 2003. Before 2003, the degree of land use in Sichuan Province decreased year by year, and began to increase slowly in 2004. During the study period, the urban land use efficiency and the ecological environment quality of land use in Sichuan Province showed an increasing trend year by year.

(2) According to the results of systematic cluster analysis, the urban land intensive use level of prefecture-level cities in Sichuan Province is divided into four categories. Generally speaking, most cities with high level of urban land intensive use are located in areas with relatively developed secondary and tertiary industries and perfect urban infrastructure in Sichuan Basin, while some old cities with traditional agriculture as their pillar industries score relatively low. The level of urban land intensive use is basically consistent with the comprehensive strength of cities in the province, and is positively related to the overall level of economic development. During the period of 1999~2004, there were obvious differences in the level of intensive land use among cities in Sichuan Province, but this gap showed a decreasing trend during the study period.

(3) 1999 ~ 2004, the level of urban land intensive use in Neijiang City and Guang 'an City was obviously improved; The level of urban land intensive use in Guangyuan City, Suining City, Meishan City, Bazhong City and Ya 'an City has not been significantly improved; However, the level of urban land intensive use in Chengdu, Panzhihua, Mianyang, Leshan, Nanchong and Dazhou has declined, but the decline is not significant; The level of urban land intensive use in Zigong, Luzhou, Deyang, Yibin and Ziyang dropped significantly.

(4) The research results of influencing factors of land intensive use show that the level of land input has the greatest influence on the level of urban land intensive use in Sichuan, and the ecological environment quality of land use has the least influence. It shows that the intensive use of land in the surrounding cities of Sichuan Province is mainly realized through land input, and economic factors are the main factors affecting the intensive use of urban land.
