Water-source reservation districts of hillside can change in land use after passing environment impact assessment (EIA), for example village education facilities, safety facilities, retailing and service business,in-building recreation, facilities etc. Some people gain benefits and other people gain loss, so it''''s not fair.
This study aims at an analysis in nature environment, pollution, landuse and land price in the water-source reservation districts of hillside,and a reference to some laws and study reports, and with the relation factor analysis, and local survey and interviews with professionals and experts. Then land use development mathematics model of price change can be established.
There are seventeen effective land-price factors at water-source reservation districts: hillsides slope, highway, elementary school, water works, police station, activity center, power-phone construction, tourist hotel, the scale of pig farms, water pipes, the distance of pig farms, the center of country and town, geology, soil, hydrolysis, streampollution, and land use. According to the result of the factor analysis, it can be ascribed to three factors, including facilities-convenient, nature-society, environment-quality.
In order to prove the model's fitness, the study of actual example andapplication-the village up the river of Kao-Ping Stream, Law-Long Streamas an example, Luh-Guei Shieng. The study uses Stepwise Regression to established the land price model of pronounce land value and actual dealing price. The result is that among the effective factors of pronounce land value in water-source reservation districts, highway, elementary school, power-phone construction and the distance of pig farms. Only the factor of highway commit expected information. The effective factors of the actual dealing price are hillside slope, highway, power-phone construction, land use, and all factors commit expected information.
The variance of land price can be known through the difference of pronounce land value and the actual exchange price. The study not only constructs the calculating equation of the pronounce land value and the actual dealing price, but also suggests land use reward fee and pollution compensation fee be collected from the said difference to achieve the principle of social justice.
