Zhang, W., 2020. A method for monitoring the spatial distribution of nutrients from the perspective of landscape ecology. In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 182–186. Coconut Creek (Florida), ISSN 0749-0208.

In order to quantify the spatial distribution characteristics of nutrient salts and monitor the ecological landscape characteristics of the spatial distribution of nutrients, a monitoring model based on fuzzy set theory for spatial distribution of ecological landscape characteristics of nutrient salts is proposed, in which the spatial distribution of nutrient salts is used to cluster the ecological landscape. The fuzzy constraint parameter model of ecological landscape feature monitoring of spatial distribution of nutrient salts is constructed based on the constraint index set, such as beauty, landscape natural fusion and energy saving and environmental protection, and so on. The analytic hierarchy process (AHP) is used to construct the statistical analysis model of spatial distribution monitoring of nutrient salts from the perspective of landscape ecology, and the fuzzy set theory is used to design the optimal control model of the monitoring model of spatial distribution characteristics of nutrient salts. The ecological landscape feature monitoring problem of nutrient spatial distribution is transformed into the binary programming problem of seeking fuzzy set. The spatial distribution characteristic map analysis and principal component feature extraction method of nutrient salt are adopted. The spatial distribution of nutrient salts in landscape is optimized to monitor the spatial distribution characteristics of nutrient salts. The results of empirical analysis show that the monitoring of ecological landscape characteristics of spatial distribution of nutrients is more accurate, more stable and more efficient.
