What do the characteristics of geographical landscape combination mean?

The so-called geographical landscape combination is an important issue in tourism geography. It means that within a region, tourist landscapes are combined into certain landscape clusters with tourist value due to geographical connections, which we call regional combinations. This combination may be caused by spontaneous clustering due to the ornamental nature of the landscape itself (that is, people's spontaneous connection with their viewing), or it may be caused by external reasons (such as the opening of tourist reserves).

To look at its characteristics, one is to look at the cluster status, whether there are more or less; the other is to look at the type of landscape, whether there are more or less, the correlation between each other is large or small, and the third is to look at the effectiveness of the combination
