Cultivated land use layout adjustment (CLULA) based on crop planting suitability is the refinement and deepening of land use transformation, which is of great significance for optimizing the allocation of cultivated land resources and ensuring food security. At present, people rarely consider the land suitability of crops when using cultivated land, resulting in an imbalance between crop distribution and resource conditions such as water, heat, and soil, and adversely affects the ecological security and utilization efficiency of cultivated land. To alleviate China’s grain planting structural imbalance and efficiency loss, this paper based on the planting suitability of main food crops (rice, soybean, and maize) to adjust and optimize the cultivated land use layout (CLUL) in the typical counties of the main grain production area in Northeast China, using the agent-based model for optimal land allocation (AgentLA) and GIS technology. Findings from the study show that: (1) The planting suitability of rice, soybean, and maize in the region is obviously different. Among them, the suitability level of soybean and maize is high, and that of rice is low. The current CLUL of the food crops needs to be further optimized and adjusted. (2) By optimizing the layout of rice, soybean, and maize, the planting suitability level of the food crops and the concentration level of the CLUL spatial pattern have been improved. (3) The plan for CLULA is formulated: The study area is divided into rice stable production area, maize-soybean rotation area, maize dominant area, and soybean dominant area, and town or village is identified as the implementation unit of CLULA. The plan for CLULA will be conducive to the concentrated farming of food crops according to the suitable natural conditions and management level. The research realized the optimization of spatial structure and cultivated land use patterns of different food crops integrating farming with protecting land. The significance of the study is that it provides a scientific basis and guidance for adjusting the regional planting structure and solving the problem of food structural imbalance.

In the context of global warming and rising sea levels, as urbanization continues to increase, the risk situation of urban systems facing floods has become more severe. Therefore, we constructed a vulnerability assessment model for urban flood disasters in Jiangsu Province, focusing on using GIS technology to classify the land use of each city in Jiangsu Province for supervised learning. We also established a flood disaster vulnerability model to evaluate the Vulnerability of 13 cities in Jiangsu Province. Evaluation and analysis of the changes in land use vulnerability use flood disasters in Jiangsu Province from 2000 to 2020. The results show that from 2000 to 2020, the Vulnerability to flooding disasters is on the rise as a whole. Yancheng has the lowest average Vulnerability to flooding disasters due to the low population density and high greening rate in the built-up area. On the other hand, Nantong City has the most heightened average flood vulnerability due to excessive population density. The low greening rate in built-up areas has led to a worsening of flood vulnerability. Suggestions have been made to reduce the Vulnerability of urban floods in Jiangsu Province, such as vigorously developing the local economy, reasonably adjusting the rate of urbanization, and building drainage infrastructure.

Old City Renewal

Along with the increasing development of Chinese urbanization, there have been a lot of cities facing the problem of old city renewal. However, during the process of re-plan and reconstruction of the old city, there is a series of changing that refers to the changing of land-use function, adjustment of land layout and the improvement of development intensity, which would change the load and setting of the urban infrastructures. Therefore, how to renew the municipal facilities safely and effectively to guarantee the routine life of people has become a crucial problem in the old city renewal. This paper takes the case study of Hengdaohezi town emphasizing the discussion on re-planning the municipal facilities in the process of old city renewal. Here, the author suggested that municipal facility planning should be carried out under the premise of safety and reliability. In the process of analysis, it should give consideration on the change of urban function and character as well, in order to make the municipal facility planning more scientific and reasonable providing support for the old city renewal from the perspective of municipal engineering.

This research is aiming at the changing land use from agricultural land to photovoltaic power plant. Geographic information system (GIS) technology was used to indicate the unsuitable areas for five economic crops that are paddy, sugar cane, maize, cassava and para rubber. The assess cost, income, and CO2 emission of the economic crops and photovoltaic power plant are the major factors for the unsuitable agricultural land deciding that will be changed to build photovoltaic power plant. The results found that the unsuitable areas for the 5 economic crops are 241,142 rai and the average solar irradiance is 17.6 MJ/m2.day for this areas which is suitable to build the photovoltaic power plant. The profit/losing of paddy, sugar cane, maize, cassava and para rubber in the suitable areas are-1,193 baht/ton, 33 baht/ton, 85 baht/ton, 259 baht/ton and-9,150 baht/ton, respectively while photovoltaic power plant cost and income are 4.12 baht/kWh and 5.65 baht/kWh respectively. CO2 emission of paddy, sugar cane, maize, cassava, para rubber and photovoltaic power plant are 2,315 kgCO2eq/tonpaddy, 37.15 kgCO2eq/ton, 256.12 kgCO2eq/ton, 29.07 kgCO2eq/ton, 153 kgCO2eq/ton and-0.5743 kgCO2eq/kWh, respectively. From these results, land use changing from economic crops planting in unsuitable areas to build photovoltaic power plant is appropriate and worth in the environmental and the economic aspect.

Ecological land use is an important component of ecosystem. This study presents spatial and temporal pattern evolution characteristics of ecological land for the period from 2009 to 2017, based on GIS technology and mathematical statistics. The results show that ecological land structure is stable, amount tends to decrease, average annual decrease of 21, 000 hm2. Ecological land types were mainly transformed into farmland and urban land, Internal transformed mainly between woodland and grassland. Spatial aggregation were existed, Aggregation degree: forest land > grassland > water area and wetland > desert. But high concentration areas (“HH” related area) is reduced from 11 counties to 9 counties, and low concentration areas (“LL” related areas) increased from 37 counties to 40 counties, from 2009 to 2017. According to the results, proposals for ecological land use were put forward.
