The development of unplanned shrimp aquaculture has caused many environmental issues and multiuser conflicts worldwide due to the lack of ecosystem characteristics‐based comprehensive methodology for identifying suitable areas for aquaculture development. This study was conducted to identify proper zones for P. Vannamei farming using the analytical hierarchy process‐based spatial analysis. Seventeen thematic layers were grouped into four fundamental requisite for P. vannamei aquaculture, namely, land class, water (pH, temperature, salinity, dissolved oxygen, turbidity, total ammonia nitrogen, nitrate, and phosphate), soil (pH, electrical conductivity, organic carbon, and texture), and resource availability (distance to road, source water, hatchery, and processing facility). The pairwise comparison matrix and the weighted linear combination approach were used. The suitability scores were classified on a scale from 1 (unsuitable) to 4 (most suitable). The spatial restriction rules excluded the regulated areas, including agriculture, mangroves, forest, settlements, water bodies, regions near the high tide line. The entire study area is favorable for P. vannamei culture in terms of water, soil, and infrastructure; however, land availability is restricted to 35,032 ha. Of the available area, 24,420 ha was found most suitable, and 10,603 ha was suitable for P. vannamei culture. The major water bodies, namely, the Buckingham Canal, Kandaleru River, and Penneru River, can support 34, 23, and 25% of the shrimp culture area. The final area outputs were compared with ground truth survey data and found to be consistent. The geospatial application of this methodology provides an integrated site evaluation for P. vannamei shrimp culture taking into environmental conditions and regulations.

基于生态系统特征和环境法规的地理空间规划，以实现可持续水产养殖发展

由于缺乏基于生态系统特征的综合方法来确定适合水产养殖发展的区域，无计划虾水产养殖的发展在全球范围内引起了许多环境问题和多用户冲突。这项研究的目的是使用基于层次分析法的空间分析方法，为南美白对虾养殖确定合适的区域。十七个主题层被分为南美白对虾的四个基本条件水产养殖，即土地类别，水（pH，温度，盐度，溶解氧，浊度，总氨氮，硝酸盐和磷酸盐），土壤（pH，电导率，有机碳和质地）和资源可利用性（距离道路，水源，孵化场和加工设施）。使用成对比较矩阵和加权线性组合方法。适宜性评分按从1（不合适）到4（最合适）的等级进行分类。空间限制规则排除了受管制区域，包括农业，红树林，森林，定居点，水体，涨潮线附近的区域。整个研究区对南美白对虾都有利在水，土壤和基础设施方面的文化；但是，土地可用量限制为35,032公顷。在可用面积中，发现最适合的面积为24,420公顷，最适合南美白对虾养殖的面积为10,603公顷。主要水域，即白金汉运河，坎达莱鲁河和彭纳鲁河，可以支撑虾类养殖面积的34％，23％和25％。将最终区域的产出与真实情况调查数据进行比较，发现结果是一致的。该方法的地理空间应用考虑了环境条件和法规，为南美白对虾养殖提供了综合的场地评估。
