- Abstract:
-
Hongsibu District of Ningxia, the largest ecological immigrant settlement area in China was selected as the case of study. The index system of evaluation of health of land use system was constructed based on PSR model. Land use health of resettlement area was evaluated by using the methods of entropy method, comprehensive index and gray relational degree. The results showed that the health evaluation index of land use system of Hongsibu Ecological Resettlement Area presented the increasing trend year by year from 2009 to 2015, increased from 0.310 9 in 2009 to 0.692 7 in 2015, and its health level rose from unhealthy to sub-healthy state; during the study period, the pressure index of land use system changed steadily, and the state index and response index showed the upward trend; due to the great differences in natural ecological environment and socio-economic development level, the spatial pattern of land use system health level changed significantly during the study period; natural population growth rate, population and land load, urban green space coverage, air quality status, urban sewage treatment rate and garbage harmlessness treatment rate, and the amount of environmental protection investment and other indicators were related to comprehensive index of health evaluation of land use system. The higher degree indicated that the health status of land use in the study area was inseparable from the population and the quality of the ecological environment. Therefore, with respect to improving the land use efficiency and formulating relevant land planning and policies in the study area, attention should be paid to the impacts of population and ecology on the sustainable development of land use.
