The integrity is referred to judge the wholeness and intactness of cultural and natural heritages. It integrity thereby depends on the extent to which the features as below can be met:
a)-All the factors that help present the outstanding universal values;
b)-Physically big enough to completely represent the features and process that present the values of heritages;
c)-Impacts by development could be neglected.

According to the Criteria I-VI, all the geographical formation and (or) vital features of application heritages shall be well conserved, and any erosion shall be under effective control. Most of the necessary factors shall be included; and for cultural landscapes, historic towns and other living heritages, all the relations and dynamic mechanisms that present the prominent features shall be conserved as well.

According to the Criteria VII-X, the biological and physical process, and landform features of application heritages shall be relatively integral. However, any region can not be kept original, because the nature is always changing-and to some extent is involved in ecologically-sustainable human activities of both traditional societies and local communities. And such human activities are considered to be in accord with natural regions that have outstanding universal values. 

Furthermore, as for the application heritages, each and every criterion from VII-X has set a respective requirement of integrity.

According to criterion VII, application heritages shall have outstanding universal values, and the site shall be big/wide enough to conserve the beautifulness. For example, the landscape value of a heritage site lies in its waterfall; and only taking into full consideration the closely-related reservoir or lake and the lower reaches, can the aesthetic value of the heritage be presented, and the integrity requirement is met.

According to criterion VIII, application heritages shall comprise all or most of the vital interrelated and interdependent factors that exist in the natural relations of the heritages. For example, the integrity requirement of a Glacier Period site shall include snowfields, glaciers, section samples, sediments, colonisation (such as striation, moraines, and pioneer stage of primary succession); and if it is a volcano, the lava shall be integral, and can represent all or most types of lava and eruption.

According to criterion IX, application heritages shall be big/wide enough and comprise necessary factors that reveal the important process of the long-term protection of the internal eco system and biodiversity. For example, in order to meet the integrity requirement, the tropical rainforest region shall have: diversified landforms and soils that exhibit certain variations above sea level; coenosis system; and natural communities. Coral reefs alike shall include seaweeds, mangroves and other nearby ecosystem that provides nutritive sediments.

According to criterion X, application heritages shall have vital values concerning biodiversity protecting. Only heritages, which have the utmost biodiversity and representativeness, can meet the criterion; and such heritages shall include habitats that present the features of diversified fauna and flora species in a biological zone or ecosystem. For example, in order to meet the integrity requirement, the savanna shall have complete, co-evolving herbivorous animals, and flora; the ecosystem of an island shall include native ecological habitats; heritages with diversified species shall be big/wide enough to include the most important habitats to ensure the survival of these species; and if a region has migrating species, the seasonal breeding places-wherever they are located-shall be properly protected.
