- Abstract:
-
Assessment on multi-functionality of land use is the key problem in multifunctional land use. We designed an identification system of multifunctional land use according to the productive, social and ecological factors and used the entire-array-polygon indictor method to measure the state of land use functions in 1990, 2000 and 2010, as well as the change in Hu’nan Province. The results show that: (1) the entire-array-polygon indictor method has advantages in multifunctional land use assessment, which takes various factors into account and reduces the influence of subjective factors, so the entire-array-polygon indictor method improves the objectivity and scientificity of multifunctional land use assessment; (2) the total function of land use had dynamic change and had improved from 0.1 in 1990 to 0.22 in 2000 and 0.40 in 2010, the center of land use turned from agriculture production function in the former period to economic production and life function (LEF) in the latter period, and there was a gradually decrease in 20 years; (3) during the study period, except function decrease of food production, the economy production, transportation security, social security, employment security, residential function as well as ecological function were increasing on different degrees. It is suggested to stabilize and improve the ecological function, improve the food production function, employment security, social security, and promote coordinated development of the functions.
