The group used a variety of factor to determine which communities would qualify to be designated as a green zone. The group that decides what will be done to reach these goals is comprised of 11 community member and four city staff, who recommend to the City Council a plan with multiple actions to be done, which must then be approved by the Council. Some of the plans to help achieve the goals in the resolution are incentives, such as lower tax rates, for businesses to reduce emissions. Washington D.
The plan includes permeable surface materials, tree canopy regulations, and other environmental and socioeconomic improvements. Alexandria, VA, Old Town North Small Area Plan: Eco-District Alexandria developed a comprehensive plan for an area with multiple aspects of sustainability and is planning on tracking the area over time to assess the impact of the plan.
Chapter 1. The agricultural land suitability evaluation of each index. The relationship between geological environment and the construction land is the complex interaction. On the one hand, urban safety is the basic condition of human survival, and the suitability of geological environment conditions determine the safety of urban construction.
Besides, urban construction process is also transforming the surrounding geological environment, which may lead to the deteriorate of regional geological conditions or exacerbate occur adverse geological effects, so it will affect the survival safety.
In the evaluation index system of construction land suitability, the landforms affect the determination of urban location, selection of urban construction site, zoning layout, engineering facilities, layout of construction and other aspects.
Because the terrain is flat, which is favorable to develop urban construction, and the terrain slope of the larger hills and mountain areas, where difficulty of urban construction has increased significantly, so the landforms has an important impact on construction land zoning Fig. The level of groundwater mineralization reflects the corrosive nature of anions and cations for underground infrastructure to affect the safety and stability of the buildings Fig.
The area where karst water distributed is a high prone area for ground collapse, which endangers the safety of surface buildings Fig. The fault condition reflects the structural stability of the area. Owing to fault slip, buildings on active faults after the earthquake, which is more prone to damage Fig.
Ground subsidence can cause the foundation to be disturbed and destroyed, which can cause the buildings to tilt, wall cracking, and even affect the normal use Fig. The higher the degree of geological hazards, the greater the likelihood of damage to buildings Fig. The type of foundation soil is directly related to the stability of the foundation, the clay soil is prone to shear failure under the action of the load, and the liquefiable soil can cause the foundation failure during the earthquake, muddy soil with stand lower loads, which is more prone to ground subsidence Fig.
Therefore, from the perspective of geological environment which affects the safety of urban land construction, selects the suitability evaluation index system of construction land Table 4. The construction land suitability evaluation of each index. Based on the present conditions of evaluation index of suitability, according to the evaluation index grading standard of agricultural land, construction land Tables 3 , 4 , with the support of MapGIS platform, the research superimposes each suitability index zoning results Figs 6 , and 7.
And use the attribute boundary of each evaluation index after superimposition serves as the evaluation unit. According to the land suitability evaluation type of grading criteria Table 5 , the results of land suitability zoning are got in the study area Figs 8 , and 9. Based on the actual conditions of land utilization in the study area, the mining land, protected area of geological relics and protected area of groundwater resources are extracted separately, which have special effects on local social economic development and ecological security.
Mineral resources and land resources are essential for human survival and social development of the means of production. The exploitation of mineral resources stimulates the local socio-economic development, meanwhile, the exploitation of mineral resources damages the arable land resources.
The non-metallic mineral resources are the main mineral resources in the study area. And although the study area has a large variety of minerals, yet the scale of mineral resources is smaller, which is mostly distributed in hilly areas outside the study area where the ecological environment more superior Fig. Furthermore, mineral exploitation is relatively great difficulty and causes large damage to ecological environment.
Geological relics are non-renewable, geological and natural heritage, with important scientific value and social value. Geological relics not only promote tourism development but also play an important role in improving the quality of regional ecological environment As the destruction of geological relics by exploitation of mineral resources and other human indexes are becoming increasingly serious 56 , geological relics of exploitation and management should be based on the protected Fig.
In addition to retaining the mining land and protected area of geological relics distributed on the construction land, respectively, the rest is classified into the corresponding land types. With the industrial development, the groundwater environment is suffered serious damage 57 , it directly relates the groundwater quality in protected area of groundwater resources and the local drinking water safety. The contamination of groundwater with hidden and difficult control properties, so the groundwater resources area should be protected in advance Fig.
This study directly divides the type of groundwater source into an ecological land buffer. According to the determination steps of land utilization and Fig. Based on the result of the land utilization zoning, the study analyses the distribution characteristics of the land utilization types, considered the suitability distribution of different land utilization types, the actual conditions, the regional function orientation and the requirement of ecological construction, the comprehensive zoning of land utilization in the study area is got Fig.
Agricultural land is widely distributed in areas with flat terrain within the study area. The low hills surrounding the study area, the terrain has a large slope, less agricultural land; The land with high agricultural suitability in the study area is mostly distributed in Jiangmen City and Huizhou City. The terrain has small slope, superior climatic conditions, good water quality conditions, superior location conditions, a certain agricultural foundation and suitable for large-scale mechanized operation of agriculture.
For some moderate suitable agricultural land distribution in the northern part of the study area, due to scattered distribution and difficult development, on the premise that it cannot be converted into construction land, it should be classified as ecological land. In Guangzhou City, Foshan City and Dongguan City, where economic development is high, water and soil are highly polluted, and they are more easily absorbed by crops, thus affecting human health.
At the same time, the population density in this area is highly concentrated, the per capita construction land area is low, part of the agricultural land in this region is divided into construction land to alleviate the tension between the supply and demand of the people in the study area. Rapid urbanization has brought serious geological environmental problems, land resource utilization seriously restricts social development. Taking Pearl River Delta Economic Zone as an example, a variable weight-analytical hierarchy process-comprehensive index evaluation model was proposed to land utilization types zoning.
In this process, based on Pearl River Delta Geological Survey Data, the model takes ecological protection zoning for the study area from assessing the importance of ecological service function in four aspects: biodiversity, water conservation, soil conservation and coastal zone protection. Based on this, the evaluation index system was established from the perspective of geological environment to evaluate the suitability of agricultural land and construction land.
And re-zoning the type of land that has a special effect on the socio-economic and the ecology. According to the actual land utilization status and land suitability distribution, the results of land utilization zoning is got.
The results showed that the area of ecological land, agricultural land and construction area in the study area accounted for Overall, the results show that the current land utilization in the Pearl River Delta is unreasonable because it does not consider geological environmental conditions, resulting in a decline in ecological service functions. This study provides an experience for regional zoning of multiple land utilization types.
The method proposed in this paper, which applies future land utilization zoning in the study area and it can be recommended to conduct regional zoning for deterioration of ecological environment and the intensification of conflicts between people and land.
