- Abstract:
-
With respect to the unreasonable agriculture water and land structure and difficult to bring into full playing the system effectiveness, taking Jiansanjiang branch 2011 data as an example, the complex adaptive allocation model of regional agricultural water and soil resources can be built by the complex adaptive system idea, and the agriculture water and soil resource optimization allocation can be evolutionarily analyzed. The results show that the agricultural output value and food production are increasing with the increase of groundwater resources, the ecological area reduces in a specific range. The efficient utilization land reduction due to the amount of groundwater mining is restricted, which leads to ineffective use of large land, seriously hindering the coupling of regional water and land resources and local economic development. It is the adaptive performance that the non-linear relationship and the sensitive degree of each subsystem for water amount change. It is of great theory and practice significance to guide scientific and reasonable development and utilization agricultural water and soil resources and improve the use efficiency of agricultural water and soil resources.
