“…Teniendo en cuenta el enunciado de Tobler: "todo está relacionado con todo, pero las cosas próximas están más relacionadas que las distantes" (Tobler, W., 1979), con este criterio se pretende precisamente evitar la selección como área equivalente de áreas que sean vecinas de la experimental, pues pretendemos evitar los posibles procesos de difusión espacial, entendidos como la acción, y el resultado de la acción, de expandirse, o de transmitir y propagar de manera uniforme los efectos de la actuación practicada en las áreas experimentales. Es decir, queremos comparar dos barrios similares pero no nos interesa que sean vecinos, pues entre barrios vecinos existirá mayor posibilidad de producirse procesos de difusión.…”

“…As a dynamical model of spatial-temporal features, CA isn"t only utilized to simulate and analyze ordinary complex systems, but also has great advantages in simulating urban system. Tobler, from University of Michigan, formally simulated the development of Detroit of Great Lakes for the first time in 1970s [15]. Thereafter, Helen Couclelis [16], Batty [17], Clarke [18], Li and Yeh [19] successively studied geographical and urban cellular automata, who made a good many meaningful achievements.…”

Abstract-Complex system theory has made people recognize and understand urban phenomena from a new perspective. In particular, The research method of the complex system has provided a powerful tool to explore problems of urban system. In this paper, basic theories of research on complexity science and complex system are described, the necessity of dynamic modeling and simulation methods as well as general steps are analyzed for the complex system. Based on this, the complexity of urban system is discussed and analyzed. Besides, the means by which dynamic simulation methods of complex system are applied in studying urban system and their significances are discussed. The result shows that it is necessary to depict, analyze and know about problems on urban complexity and explore deeper rules hidden in dynamical urban development with the theoretical framework of complexity science, so as to better interpret, design and plan cities.Index Terms-Complexity science, CA, MAS, urban system. I. INTRODUCTIONWith the rapid development of cities and constant integration of disciplines, urban planning has increasingly become a discipline not purely focusing on designing physical forms, but has also begun to pay great attention to other non-physical factors (e.g. human and society) and more fundamental rules hidden in dynamic development of cities. Studied by urban planners, urban system is becoming more and more complex in both forms and nature. Thus, how to understand, analyze and depict such a complex system has become an urgent problem to be solved by planners. Traditional research methods based on reductive thinking encounter great challenges in interpreting the formation of urban structure, urban spatial evolution and laws of human activities in cities, etc, which fail to reveal deeper causes and rules of dynamic urban development.By the end of 1980s, the founding of Santa Fe Institute directly facilitated and led to the emergence of complexity science. The complexity science had achieved rapid development within less than 20 years and has become the focus of attention in the scientific field at present. On one hand, the theories of complexity science greatly change people"s ideas of urban system. On the other hand, research methods of complex system particularly make powerful means available to explore urban system.

“…No caso de projetos de assentamento, a localidade i refere-se a um lote e a distância d define a área de vizinhança de cada lote. É esperado que lotes próximos apresentem taxas de malária semelhantes (Primeira Lei da Geografia de Tobler, 1979). Valores padronizados do teste G i * (d) são comparados com a distribuição estatística normal, a fim de identificar a presença de conglomerados significativos (GETIS; ORD, 1992;GETIS, 1995).…”

“…Através de funções matemáticas, essa estrutura espacial permite o cálculo de pesos que, multiplicados pelos valores observados, resultam em estimativas para os pontos não amostrados. Conforme a Primeira Lei da Geografia (TOBLER, 1979), esses pesos são maiores para localidades próximas e menores para aquelas distantes. Cressie (1991) apresenta detalhes do modelo de krigagem e dos procedimentos de estimação.…”

IntroduçãoA malária é provavelmente tão antiga quanto a espécie humana, porém sua etiologia só foi descoberta no final do século XIX. Em 1898, Ronald Ross provou que o vetor de transmissão era o mosquito. Alguns anos antes, em 1880, Charles-Louis-Alphonse Laveran foi o primeiro a identificar o parasita da malária no microscópio (DESOWITZ, 1991). Em 1820, o quinino começou a ser produzido em larga escala, permanecendo como única droga para tratamento da malária por cerca de 110 anos (BOYD, 1949; JARCHO; TORTI, 1993). Em 1905, Carlos Chagas estabeleceu a importância das condições da habitação para a transmissão da doença, sugerindo o uso de telas e a fumigação das casas pelo vapor de enxofre (CHAGAS, 1934;SILVEIRA;REZENDE, 2001). Pela primeira vez foi caracterizado o conceito de malária como doença domiciliar, raramente adquirida no exterior do domicílio, e foi adotada medida visando a eliminação do mosquito transmissor (DEANE, 1986). Em 1940 Paul Müller patenteou o DDTque permite eliminar mosquitos presentes no interior de domicílios através da borrifação (DESOWITZ, 1991). Com base nesse conhecimento adquirido desde o final do
