| 内容記述 | Preparing water resources is a principal problem to introduce a new irrigation system in mountainous areas where have poor water sources. From 2003 to 2005, we promoted a project aiming to introduce water saving irrigation system by using small irrigator (pulsator) into the mountainous area, and this paper shows the results of a research conducted in the project. The object of the research is to improve water quality of an abandoned and polluted small reservoir (940m^3 in volume located at Takase in Kagawa Japan) to utilize as a water resource of the water saving irrigation system through dilution of the ponding water by pouring rain water fallen on greenhouses into the small reservoir was experimented as a new method. As a result, the following is clarified. 1 Pouring rain water from greenhouses into the reservoir was followed by decrease of values of EC (from 250 to around 100μS/cm), pH (from 9.5 to around 7.0), turbidity (from 100-200 to 20-30 degree) and concentrations of ions such as Cl^-, NO_3-N, SO^2-_4, Na^+, Ca^2+, and this method can improve effectively water quality of polluted small reservoir. 2 Change in EC value while pouring rain water can described well through two processes, one is decrease due to poured rain water which is in proportion to amount of rainfall, and the other is countervailing increase which is in proportion to days of no rain. 3 In case of the reservoir of 940m^3, it was presumed that greenhouse roof area of more than 520m^2 was required for stable effect of the water quality improvement, through the simulation using two processes above. 4 Also, it was conjectured through the simulation that more than 250m^2 roof areas to a reservoir of 500m^3 and more than 1100m^2 roof areas to a reservoir of 2000m^3 was required respectively to acquire the similar effect of the case the 940m^3 reservoir. In this research, the mechanism of the countervailing increase of EC could not be clarified, and change in EC value also could not be generalized because of complicated phenomena. So, the results of the research can apply just to the reservoirs which show similar properties of countervailing increase of EC. However, the effects of a new improvement method of water quality can be showed. Hereafter, change in water quality in the reservoir should be clarified more in detail to generalize this method. | |||||||||||||||||||||||
