Explore the spatial relationship between farml and use changes and farml and transactions

The conventional land use Policy tends to release farmland to achieve economic development and satisfy land use demand and resulted in the conversion of farmland into nonfarm uses. In 2000, farmland ownership has been greatly released and enterprise capital has been allowed to enter farmland market. Farmland transactions have become leading index of farmland use changes in urban fringe. Developers are often willing to pay a premium and further encourage farmland transactions and the frequent change on farmland ownerships. We subject data from Tainan County (with boundaries as recognized prior to the changes of 2011) for spatial features of farmland transactions and on farmland use changes to certain spatial relationship analyses after the release of farmland ownership. The results show that the conversions of farmland use change have happened in study area, of whichconverted to industrial and residential uses wereresulting in negative impacts on the remaining surrounding farmlands. In addition, transacted farmland changed to transportation, nonfarm structures and public facilitiesappear to cluster together in urban fringe. Moreover, the results of bivariate LISA statisticshow thatthe moderately positive spatial relationship represents similar spatial features for both farmland use changes and farmland transactions in neighborhoods close to each other resulting in clustered patterns, and the clustered patterns decrease with distance which shows that farmland use changes values are associated with farmland transactionsunder certainproximity.
