Land Registration System in PHP

Accurate spatial distribution of agricultural population which accounts for the largest proportion of the whole country in China is pretty suggestive to the resources adjustment and regions development. It is difficult to describe the internal situation of the statistical unit when using statistic data of administrative area to research population distribution for most of the previous studies. The project of registration and certification for rural contracted land has collected detailed information about contracted land and peasant household as well as the contract relationship between them. In this study we start with assignment of the family members to each piece of land that contracted by the peasant household. Then the contracted land with proportion of family members is assigned to the grid via position to simulate the spatial distribution of agricultural population. Compared with using statistic data of administrative area, the result of agricultural population distribution produced using rural contracted land registration and certification data is considered to be more accurate and detailed.
