Sentence fragments are incomplete sentences. They may be caused by different problems. See also Punctuation.
In example 1, there is a clause (i.e. a dependent sentence) starting with a relative pronoun after a full stop, but there is no main clause.

Missing main verb

 
In example 2, there is no main (finite) verb. Instead, there is a non-finite form (i.e. reducing) which can never be a main verb.

2.

Hong Kong’s shoreline ecology will be altered by extensive land reclamation and heavy shipping traffic which will affect the diversity of intertidal, seabed, and coral communities.

 

In example 3, there is no main clause because the two clauses contain a subordinating conjunction (i.e. “since,” “as”). You can have a main clause by deleting “since”.
 

 

WRONG
RIGHT

Victoria Harbour is very important for Hong Kong. Since, it is a key asset of Hong Kong as it completely represents Hong Kong’s history and values.

In example 4, a main verb is missing in the subordinate clause “that my perseverance, intellectual ability and enthusiasm for learning and working.” You can have a grammatical sentence by deleting “that”.
 
WRONG
RIGHT

4.

She has praised that my perseverance, intellectual ability and enthusiasm for learning and working. She has praised ø my perseverance, intellectual ability and enthusiasm for learning and working.

 

In example 5, the sentence becomes incomplete without the main verb (i.e. “is”).
 

 

WRONG
RIGHT

5.

Victoria Harbour which is a symbol of the “Pearl of the Orient, _ situated between Hong Kong Island
and Kowloon.

Victoria Harbour which is a symbol of the “Pearl of the Orient, is situated between Hong Kong Island and Kowloon.

 

In example 6, the comma separates the subject from the verb, resulting in an incomplete sentence.
 

 

WRONG
RIGHT

6.

Pollution, is the main problem and water pollution is especially serious in our harbour.

Pollution ø is the main problem and water pollution is especially serious in our
harbour.

 

In  example 7, the sentence “As a result a blockage of stunning panoramic night views” is missing a main verb, because “blockage” is a noun. See also Word Class.
 

 

WRONG
RIGHT

7.

With rapid economic development, more and more skyscrapers have been built and the harbour has been surrounded. As a result a blockage of stunning panoramic night views.

With rapid economic development, more and more skyscrapers have been built and the harbour has been surrounded. This results in a blockage of stunning
panoramic night views.

 

Missing subject

In English, every sentence should have an explicit subject.

In examples 8 and 9, the subject is missing from the sentences “also brings unlimited inspirations and joy” and “accommodates over 1.8 million units of containers”.

WRONG
RIGHT

8.

For people living and working here, the harbor is more than a source of motivation, __ also brings unlimited inspirations and joy.

      Thanks for the comment.

      You have given a good example of sentence fragment because there isn’t a main clause in “As primary inputs and deliver goods and culture with services, creative and artistic content” (refer to example 3).
