Ecosystem services (ESs) value realization and ecological industry (eco-industry) are essential components of regional development. Due to the vulnerability and non-renewability of natural landscape resources in Karst areas, once unreasonable resource development takes place, it is easy to pose threats and causes damage to its ecosystem. This article selects the grain data correction equivalent factor coefficients in Guizhou Province, China, and establishes accounting indicators for Karst scenic areas. It is found that the total economic value of ESs is as follows: Shanmuhe Scenic Area (CNY 5096.3 thousand) > DaXiaoQiKong Scenic Area (CNY 2778.6 thousand) > Huangguoshu Scenic Area (CNY 2130.7 thousand). Among them, the value of regulating services plays a dominant role in the composition of ESs, and the value of forests accounts for the largest proportion. Through web crawlers, tourism data can be acquired, and the Product–Experience–Feedback–Improvement (PEFI) model can be applied to reveal that tourists have a predominantly positive perception of Karst scenic areas. This indicates that karst landscape resources are deeply loved by domestic and foreign tourists, especially mountain, water and forest landscapes. Based on the results of the ES value accounting of the scenic area and the external perception data of tourists towards the scenic area, the eco-industry spatial layout development plan is formulated. According to local conditions, the development, construction, and protection of the scenic area are carried out, jointly promoting the realization of the ecological product value (EPV) of the Karst scenic area, to determine the optimal development direction of the eco-industry, and to promote the coordinated development of ecological resources and assets.
