Garden art is the culture of generations since ancient times and is another spiritual carrier of people’s internal admiration for natural landscape, culture, and art as well as their love for living in nature and landscape. This article mainly studies the data clustering algorithm and adopts a research methodology that progresses from simple to complex. It starts by establishing a spatial data clustering model and then clustering the low-dimensional data, and then processing the high-dimensional spatial data in the low-dimensional data set. The original K-means clustering algorithm is then improved, and the new algorithm is created by combining PSO with the K-means algorithm in the high-dimensional spatial data set. And the improved two algorithms are applied to the study of data related to landscape conservation sites, and the powerful superiority of the improved K-means spatial clustering algorithm in this article is verified through the comparison of the algorithms.

En este artículo se presentan los resultados del estudio de artefactos arqueomalacológicos hallados en la costa sudeste del lago Colhué Huapi, en provincia de Chubut, Patagonia central, Argentina. Se analizan los materiales del sitio Oporto 7 y de una colección particular, que consisten en objetos de adorno personal elaborados sobre el gasterópodo terrestre Megalobulimus sp. Estos artefactos son excepcionales en Patagonia, ya que esta especie de caracol tiene una distribución biogeográfica tropical y subtropical. Se analizaron 18 piezas de adorno, lo que representa el mayor número de objetos manufacturados sobre este caracol en Patagonia central. Objetos de adorno elaborados sobre conchas de Megalobulimus sp. han sido registrados en diversos contextos arqueológicos residenciales y funerarios en Argentina y Chile. En este trabajo se discuten las implicancias en cuanto a las relaciones extra-patagónicas que pudieron entablar los grupos humanos que habitaron en inmediaciones del lago Colhué Huapi a partir de la presencia de estos bienes exóticos, los cuales permiten vincular las ocupaciones de cazadores-recolectores del Holoceno tardío en Patagonia central con áreas tan distantes como el centro y norte de Argentina.

Buena Pinta Cave (Pinilla del Valle, Madrid) has been interpreted as a hyena den with sporadic occupations of Homo neanderthalensis in the western part of the site (level 23). In order to identify the different formation processes in this area of the site, spatial analyses have been carried out with GIS and spatial statistics based on the taphonomic analysis of the faunal remains. Based on the vertical and sectional analyses of the assemblage, it has been possible to determine that level 23 actually corresponds to three archaeological levels with well-differentiated characteristics: a lower level with few faunal remains and fossil-diagenetic alterations related to humid environments associated with clays; an intermediate level with a high percentage of remains with water-related modifications and evidences of transport; and an upper level delimited mainly thanks to by a paraconformity evidenced by the concentration of weathered remains in this area and a significant reduction in remains with water-related alterations above. The results obtained show the necessity to redefine field layers and the usefulness of integrating taphonomic data and spatial studies.
