Study On Land Productivity Potential Of HuangDao Region Based On GIS

As everyone knows,with the rapid development of China society,accelerating the urbanization process,the contradiction between population and land become more and more important and sharp,land resources is becoming a scarce resource.China is a country with a large population,person much ground is little,average per capita arable land area of the world.How to make rational use of land resources,increasing land utilization,mining land more fully the potential,has become a hot issue in today’s social studies.Based on GIS technology,through the establishment of Huangdao space-property database integration,production potential of land Huangdao District were studied.In summarizing the previous inspection method to calculate the production potential of land on the basis of the current situation in the study area,select the mechanism of law model(ie,light and temperature factorial model).For the study of the production potential of the land,taking into account the effects of light,temperature,moisture,soil and other environmental factors,the impact of various types through gradual attenuation factor,finally got the land productive potential value of Huangdao District.Meanwhile,with the powerful ArcGIS spatial analysis and mapping capabilities,has been producing all kinds of potential distribution of Huangdao District in space,and ultimately get the following conclusions:1,based on GIS technology research potential land productivity,more efficient and accurate,to the factors affecting the productive potential of the land can be considered more fully.2,through the review of previous research studies,the study of the various types of potential land productivity calculation method,the calculation model chosen for Huangdao District.Huangdao District productive potential of the land for the comprehensive analysis conducted to explore,to improve the efficiency of land use Huangdao District,planting more reasonable to improve the scientific basis.3,Soil conditions is an important factor affecting the productive potential of the land,we use AHP to determine the soil available to calculate the index weight coefficient in the model,high reliability coefficient obtained efficiently was computed.At the same time,can be calculated on the basis of soil coefficient value of the land productive potential of land grading Huangdao district.4,Huangdao District,the township streets between the potential value of the production,overall less,this is due to the small study area,the environmental factor is basically the same index.At the same time,there are various different township streets.Offshore potential value of the township streets slightly,mainly because of strong light,photosynthetic potential of great value calculated.A higher overall level of Huangdao District land use.In summary,the results of this research,consistent with the reality of the situation,can provide a basis for planning and development of agriculture,with relevant scientific significance.
