[Establishment of response system to emergency parasitic disease affairs in China].

China's prevention and control of parasitic diseases has made remarkable achievements. However, the prevalence and transmission of parasitic diseases is impacted by the complicated natural and social factors of environment, natural disasters, population movements, and so on. Therefore, there are still the risks of the outbreak of emergency parasitic diseases affairs, which may affect the control effectiveness of parasitic diseases and endanger the social stability seriously.

Objective: To improve the information level of schistosomiasis control by using the related functions of CorelDRAW software.

Methods: Combining with the requirement of schistosomiasis control, the sketch map was drawn according to the linear element drawing, the geometric drawing, the color rendering and the text adding.

Results: The schistosomiasis epidemic sketch map and the snail distribution sketch map at all levels were produced in CorelDRAW software.

[Evaluation of transmission control of schistosomiasis in 19 counties (cities, districts) of Hubei Province in 2013].

Objective: To evaluate the schistosomiasis transmission control in 19 counties (cities, districts) of Hubei Province in 2013.

Methods: The epidemic villages from different counties were randomly sampled by the cluster sampling method as the evaluation villages. The schistosome infection status of human and livestock, the snail status, the documents and data of schistosomiasis control, acute infection control and health education were investigated in the field.

[Epidemiological investigation on confirmed cases of schistosomiasis in Hubei Province].

Objective: To grasp the distribution and epidemiology of confirmed cases of schistosomiasis in Hubei Province, so as to provide the evidence for promoting the prevention and control work.

Water environmental planning considering the influence of non-linear characteristics.

In practical water environmental planning, the influence of the non-linear characteristics on the benefit of environmental investment was seldom taken into consideration. This paper demonstrates that there exist a lot of non-linear behaviors in water environment by emphatically analyzing the influence of the non-linear characteristics of the economic scale, the meandering river and the model on water environmental planning, which will make a certain impact on the water environmental planning that sometimes cannot be neglected. This paper also preliminarily explores how to integrate the non-linear characteristics into water environmental planning.
