Benton County is in the southern central part of the Washington State, USA. The population of the County in 2017 was 198171. The total area of the county is 1760 square miles with 60 square miles water. Need for general entertainment chances and sites is increasing and will grow as both the urban and rural populations of the County increase and as the growth in overall State population. The spatial control of the county needs to consider multiple factors. First, starting from a single factor, based on the adaptability to construction or the importance of protecting the ecological environment, a single factor assessment is carried out and reclassified. Secondly, spatial superposition is carried out according to the importance weight, and then the comprehensive results are evaluated to obtain the spatial control outcome. Among them, water protection area is a mandatory factor, usually called a veto factor, which does not participate in the weight superposition, but directly delineates the prohibited construction area on it after the result of weight superposition. Based on the analysis of the current status of the ecological environment, multiple ecological and environmental factors are selected: elevation factor, slope factor, terrain range feature, land use status, water conservation and basic farmland. According to the construction adaptability and importance of ecological and environmental protection of each single factor, it is divided into four levels: elevation, slope, terrain range and land use zoning. The single factor is rasterized and reclassified according to the following scoring principles: 100 points, 75 points, 50 points, 25 points. The higher the score, the more important it is to the ecological environment, and the less suitable it is for Golf Course construction and development; on the contrary, the lower the score, the smaller the contribution to the ecological environment, and the more suitable it is for Golf Course and development. ArcGIS was used throughout the evaluation and analysis process.
